Aston Villa substitutes Jhon Durán and Ross Barkley bagged second-half goals to salvage a 3-2 victory over RB Leipzig on Tuesday in a Champions League match marked by a stunning error from goalkeeper Emiliano Martínez that gifted Leipzig a goal.

With 13 points after six games, Unai Emery's men are provisionally third in the table and could be just a win away from booking clinching a spot in the top-eight of the table and an automatic place in the round of 16.

Leipzig have zero points and their loss means they cannot advance.

"I thought overall we were the better team and we could have scored more," Villa's captain John McGinn told Amazon Prime. "We dealt with their problems well and what we needed today was substitutes to come on and make a difference.

"It is exciting. It is great to be in the top three."

McGinn put Villa on the scoresheet inside three minutes when he fired in Ollie Watkins's header past Péter Gulácsi.

Loïs Openda levelled against the run of play in the 27th minute when Martinez ventured well out of his net but misjudged the bounce of the ball, allowing Openda to nudge it past him and score.

Super sub Duran, who has six goals off the bench this season -- the most by any player in Europe's big-five leagues in 2024-25 -- was electric from the moment he entered the game after the break.

He put the visitors up in the 52nd minute when he latched on to a pass from Youri Tielemans before unleashing a blistering shot from nearly 30 metres out that sailed over Gulacsi's head.

"I am just happy to be here and love the competition with Ollie Watkins," Duran said. "When it is my turn hopefully I can step up and help the team."

Duran had the ball in the back of the net again minutes later, but it was chalked off for offside in the build-up. The Colombian turns 21 on Friday and was asked after the game how he might celebrate.

"I am definitely not going out to celebrate my birthday because my aim is to score on Saturday (in a Premier League game at Nottingham Forest) to celebrate," he laughed.

Leipzig levelled 10 minutes after Duran's goal when a 40-metre pass from Benjamin Henrichs found Openda, who floated the ball to the back post for Christoph Baumgartner to steer in with a volley.

Two minutes after he entered the game, Barkley bagged a fluke winner in the 85th when he slipped while firing a shot from long range that took a big deflection off defender Lukas Klostermann and went in.

The new Champions League format sees the top eight teams in the league phase after eight rounds advance into the round of 16. The teams from ninth to 24th will go into two-legged play-offs, with the eight winners moving into the last 16.

Villa's final two games of the first round are at Monaco on Jan. 21 and against Celtic at Villa Park on Jan. 29.
