Teenage sensation Cori "Coco" Gauff has the right elements to reach the top of the women's game following her sensational Wimbledon win over Venus Williams, according to two former Grand Slam champions.

Gauff, who at 15 years and 122 days became the youngest player to qualify for the main Wimbledon draw since the Open era began in 1968, swept aside the five-time winner 6-4 6-4 on Court One in front of her jubilant parents and a packed crowd.

"People have been talking about Coco for years," fellow American and two-time US Open champion Tracy Austin told BBC's Today at Wimbledon.

"They have now started to recognise her internationally. Obviously she's a tremendous athlete, but to walk on court to face Venus, a player who she idolises, there were plenty of opportunities for her to get tight and nervous.

"She has been raised for greatness and this is beginning."

Three-time Wimbledon men's champion John McEnroe added: "Gauff's not only physically mature, but also mentally.

"I look at the way she plays. If she's not number one in world by 20 I will be absolutely shocked."

Gauff, who started playing tennis at the age of seven, comes from a sporting family. She is coached by her father Corey, who played basketball at Georgia State University while her mother Candi was a gymnast before moving into track and field.

Their daughter began to deliver in major arenas two years ago when she became the youngest US Open girls singles finalist - aged just 13. And last year she won the French Open equivalent only two months after her 14th birthday.

Wimbledon qualifying was a target for Gauff this year, but her ranking of 301 was not high enough to earn a shot. However, while she was shopping online she found out she had received a wildcard.

In the final round of qualifying she eased to a 6-1 6-1 win over Belgium's world 129 Greet Minnen, although her preparations were not ideal having had to take a science test at 11pm the previous night.

Atlanta-born Gauff idolised both Williams sisters, Venus and Serena, so when she was drawn against the elder of the two in the first round, the focus on her grew further.

How would she perform against one of the all-time greats in such a big arena?

Gauff settled into the match early, breaking to go 3-2 up in the first set then crucially breaking for 5-4 in the second before serving out for victory against a player who had already won four Grand Slams before she was born.

Gauff, herself, was "super shocked" at just beating Williams.

"Obviously, I literally got my dream draw, so I'm just super happy I was able to pull it out today," she said in her post-match news conference.

"She played amazing, was just super nice. She's always been nice the couple times I met her."

When asked about what she can achieve in the sport, the teenager said she has been given a target to "be the greatest".

"My dad told me that I could do this when I was eight," said Gauff, who is being nurtured by Serena Williams' coach Patrick Mouratoglou.

"Obviously you never believe it. I'm still, like, not 100% confident. But, like, you have to just say things. You never know what happens."

Former American world number six Chanda Rubin has also followed Gauff's career closely.

She told BBC Sport: "We've seen something incredible.

"Just 15 years of age, her very first Grand Slam main draw, a first Wimbledon main draw, against a Venus Williams who played a good match.

"I think we're seeing a champion in the making here."

Social reaction to Gauff's stunning victory

Britons Kyle Edmund and Heather Watson made their experience count to reach the second round at Wimbledon.

Edmund took his time to impose himself on Wimbledon debutant Jaume Munar in a 6-4 6-4 6-4 win, while Watson also made a shaky start against 17-year-old qualifier Caty McNally.

British number two Watson saved two set points in the first set before beating the American 7-6 (7-3) 6-2.

Edmund was error-prone in his win over resilient world number 90 Munar.

The British men's number one will face another Spaniard - former world number seven Fernando Verdasco - in the next round, while Watson takes on Estonian 20th seed Anett Kontaveit.

Edmund made to battle for victory

Edmund had come into Wimbledon after a confidence-boosting first Tour-level grass-court semi-final at Eastbourne last week.

But against Munar, the 24-year-old looked far from assured, going an early break down and later requiring 10 set points to eventually take the opener when the Spaniard sent a shot wide.

It was a similar story in the second where the 30th seed repeatedly hit long from the baseline and the tenacious Spaniard seemed to be able to get to impossible-looking shots.

Edmund had looked like would run away with the third, going 5-1 up before Munar won three games in a row.

There were encouraging signs that Edmund seemed unhampered by a knee problem that forced him to retire from his second-round match at the French Open, with the Briton racing forward for a drop shot in the seventh game of the second set and making a lob.

And he won back-to-back games to love with the perfect mix of forehand winners, an ace and a drop shot to show glimpses of the player who reached the 2018 Australian Open semi-finals.

But with 37 unforced errors - to his opponent's 20 - there were too many mistakes to back up his pre-tournament claim that he could win Wimbledon.

"I had to work hard for it for sure," Edmund said. "The guy was a really good fighter, he played with a lot of spirit.

"Hopefully I can improve from this match and make my life a little bit easier."

'Nervous' Watson pulls through

Watson, appearing in the main draw at Wimbledon for the 10th year in a row, came into the championships on the back of first-round exits at the grass-court events in Nottingham, Birmingham and Eastbourne.

She made a shaky start here, going 3-1 behind in the opening set before winning three games in a row to draw level.

There were eight breaks of serve in the first set and Watson made a desperate challenge on a McNally serve at 30-15 and 6-5 that the replay showed was well in and gave the American two set points.

But Watson unleashed a fantastic forehand down the line to save the first one and forced the American into a forehand error to save the second. To the delight of a packed court 12, she never looked back.

Another netted forehand by McNally sent it to a tie-break, which a pumped-up Watson raced through.

She kept up the momentum to go 5-1 up in the second, the only wobble coming when she needed four match points to wrap up the victory.

"I was a bit nervous today and I think it showed," said Watson, who has reached the third round three times here and won the mixed doubles title with Henri Kontinen in 2016.

"I'm a confidence player, so not having those wins in the last few weeks, I was maybe over-thinking a bit."

Watson is one of four Britons in the women's singles draw, with Johanna Konta, Katie Swan and Harriet Dart playing their first-round matches on Tuesday.

Murray's doubles partner 'feeling pressure'

While there are 10 British players in the singles main draws, the biggest home interest will be around former world number one Andy Murray's return to Grand Slam action in the men's doubles.

Imagine, then, being the 32-year-old Scot's doubles partner Pierre-Hugues Herbert and having to tell Murray you were feeling pain in one of your quads.

Except, he didn't tell him.

The Frenchman said he felt pain on Sunday but that it had gone during his first-round singles defeat by South African fourth seed Kevin Anderson 6-4 6-2 6-3 on Monday.

"I don't want to imagine me having to say anything to Andy about an injury," the 28-year-old said.

"I was scared for one of my quads. But when I did the medical tests [on Sunday], everything was fine."

He added that playing alongside Murray meant he was feeling "more pressure than ever".

"But it's something so special," he said. "I'm feeling lucky and I'm so motivated and pumped to play with Andy, and to have the luck to play with him here in Wimbledon."

Second seed Naomi Osaka has been dumped out of Wimbledon in the first round, losing 7-6 (7-4) 6-2 to Yulia Putintseva of Kazakhstan.

Japan's Osaka, the US and Australian Open champion, has suffered a dip in form in recent months and struggled throughout her match on Centre Court.

Osaka told journalists she felt like she was "about to cry" after the match.

"There are answers to questions that you guys ask that I still haven't figured out yet," said the 21-year-old.

Osaka, who became the first top-two seed to lose in the opening round at Wimbledon in the women's singles since Martina Hingis in 2001, was 3-1 up in the first set before she was broken back and edged out in the tie-break.

She was then broken in the fifth and seventh games of the second, before her 38th unforced error gave the world number 39 victory.

"I wouldn't blame my age on anything," said Osaka, after being asked if it was a factor in the defeat.

"I've done a lot of good things. I've done a lot of bad things. But I'm not the type of person that would say because I'm young I can get away with doing certain things."

Putintseva also defeated Osaka at the grass-court event in Birmingham in June and the former world number one said that played on her mind.

"I feel like I should have been able to play well today because I wasn't practising bad," she added. "You never know what's going to happen during matches."

Putintseva, 24, impressed on her first outing on Centre Court and said it was "amazing" to progress against Osaka.

"I did a good job out there. I'm very happy now," she said. "Every match is a battle, but you never know what's going to happen. I was hoping I would do my best.

"Every year I feel better on grass, although I think clay is my better surface."

The Kazakh will now face Swiss world number 81 Viktorija Golubic in the second round.

In the build-up to her opening match, Osaka said she had struggled with the "stress and pressure" of being world number one, which she earned by beating Petra Kvitova in Melbourne in January to win her second successive major.

Since that victory, she has only reached one semi-final and also lost her top ranking to French Open winner Ashleigh Barty.

On Monday, aside from the numerous unforced errors, luck also deserted the Japanese player when Putintseva's mis-hit backhand caught the edge of the line and earned her a break for 3-2 in the second set.

Osaka wasted an opportunity to break back when she fired a straightforward volley wide as her opponent grew in confidence and closed out the set.

She now has two months to put things right before her defence of her US Open title.

'Osaka has to go back to the drawing board' - analysis

Tracy Austin, two-time Grand Slam champion on BBC TV

Putintseva had a clear gameplan not to give Osaka any rhythm - nothing was at the same height. Osaka had a chance to get a break back [at 3-2 in the second set], but she looked nervous and was over hitting.

Putintseva stuck with the gameplan and so many players are able to get the set lead but not then able to hold on to it. Osaka has to go back to the drawing board. Everyone was putting her in the mix to win this tournament and she does not look comfortable.

She's one of the biggest stars in the world but so shy, and when the spotlight is on you it is overwhelming.

John McEnroe, three-time Wimbledon singles champion on BBC TV

I don't think Naomi is very comfortable on grass. You need that intensity and be on it. She just does not look like she's all there.

She's distracted. A lot of things have happened and it seems she has lost her confidence, which is amazing from where she was two or three months ago.

Fifteen-year-old American qualifier Cori Gauff caused a stunning upset by defeating five-time Wimbledon champion Venus Williams in the first round.

World number 313 Gauff beat Williams - 24 years her senior at 39 - 6-4 6-4.

Fellow American Williams had won four Grand Slam titles - including two at Wimbledon - before Gauff was born.

"It's the first time I have ever cried after winning a match," said Gauff, who previously said Venus and sister Serena were her "idols".

"I don't know how to explain how I feel.

"I definitely had to tell myself to stay calm, I had to remind myself that the lines are the same lines, the courts are the same size and after every point I told myself 'stay calm'."

Gauff will play Slovakia's Magdalena Rybarikova - 15 years her senior - in the second round.

Williams turned professional 10 years before her opponent was born, with Gauff being the youngest player to qualify for the main Wimbledon draw since the Open era began in 1968.

She previously said the Williams sisters inspired her to first pick up a tennis racquet.

"Venus told me congratulations and keep going, she said good luck and I told her thanks for everything she did," Gauff added.

"I wouldn't be here if it wasn't for her - I told her she was so inspiring and I've always wanted to tell her that but I've never had the guts to before.

"My parents will be super happy, my dad was jumping up every time I won a point. I'm so happy they spent all their time on me and my brothers and making sure we're successful.

"I never thought this would happen. I'm literally living my dream right now.

"I'm really happy Wimbledon gave me the chance to play, I never thought I would get this far."

'The sky's the limit' - a debut to remember

In a sharp introduction to the Wimbledon stage, Gauff initially struggled to return Williams' serve but she soon impressed with big serves of her own.

Gauff, who won the French Open junior title last year, went a break up on Williams for 3-2 in the first set, proving a solid wall that her veteran opponent simply couldn't break down, hitting only two unforced errors throughout the set.

After sealing the set in 35 minutes, she went a break up in the second after Williams double-faulted, only to do the same herself on her own serve as Williams looked to claw back.

She went on to scupper three match points before Williams created a break point, but she failed to capitalise on the chance as Gauff clinched a memorable win on the fourth time of asking.

It marks only the second time Williams has been beaten in the first round at Wimbledon since her 1997 debut.

Asked about Gauff's future, Williams said: "I think the sky's the limit, it really is.

"She did everything well today. She put the ball in the court, which was much better than I did. She served well, moved well. It was a great match for her."
