TOP STORY: Mandzukic to Man United?

Manchester United will need a striker once Romelu Lukaku's move to Inter Milan has gone through, and Sky Italia reports that they have set their sights on Mario Mandzukic.

Mandzukic, 33, isn't one for the future but he's a quality player with plenty of experience that would allow Marcus Rashford and Mason Greenwood to develop. In fact, sources have told ESPN that United may not even make a move for anyone as they trust 19-year-old Greenwood to fill in.

United have already spent £80m on Harry Maguire and £50m on Aaron Wan-Bissaka, while Mandzukic is a cheaper option than Athletic Bilbao's Inaki Williams who would cost £81m. The Sun reports that Williams is an option though.

09.44 BST: Tottenham are closing on two deals today. Paulo Dybala could be set to arrive for €70m, while Giovani Lo Celso looks a bit further along as the Telegraph is reporting that the midfielder is having a medical. He could cost around €60m.

09.37 BST: Borussia Dortmund defender Omer Toprak is set to join Werder Bremen, according to reports from Deichstube in Germany.

The 30-year-old wants more playing time and is prepared to see his salary halved from €5m per year.

Dortmund could receive a €5m transfer fee in return and get another player off their payroll. Felix Passlack, Alexander Isak, Abdou Diallo, Sebastian Rode, Jeremy Toljan and Andre Schurrle have already left Dortmund this summer, while Shinji Kagawa and Maximilian Philipp are also on their way out.

09.24 BST: Shock late move for Manchester City here in the goalkeeping department. Former England goalkeeper Scott Carson is set to join on a season-long loan from Derby, says the BBC.

Ederson is the undisputed No. 1 with Claudio Bravo his backup. But the 33-year-old former Leeds, Liverpool, andWest Brom stopper will be third-choice.

09.05 BST: West Ham have signed Switzerland international striker Albian Ajeti from FC Basel on a four-year deal.

09.03 BST: Swiss outlet Blick claims AS Monaco are interested in Xherdan Shaqiri and Liverpool would want €36m for the midfielder.

Shaqiri has been a great backup for the likes of Mo Salah and Sadio Mane, but the Switzerland international wants to play a more important role.

08.57 BST: Southampton striker Charlie Austin has been pushed down the pecking order after the arrival of Charlie Adam, so West Brom and Bristol City are trying to land him on loan, according to Sky Sports.

08.42 BST: Everton are exploring the possibility of signing Marcus Rojo from Manchester United after being knocked back in their approach for Chris Smalling, with a source telling ESPN FC a deal is "unlikely as it stands, but you never know."

08.28 BST: Sampdoria forward Dennis Praet will join Leicester for a fee in the region of £12-14m, a source has told ESPN.

Leicester have plenty of money to spend after selling Harry Maguire to Man United but there's no sign of a replacement centre-back just yet.

08.23 BST: Australia midfielder Aaron Mooy is set to join Brighton on loan from Huddersfield, a source has told ESPN.

Huddersfield were relegated from the top-flight last season and Mooy was one of their star players, so it makes sense that a Premier League club are interested. We're just surprised that they are letting him depart on loan.

08.15 BST: And more from the BBC, as they report that Juventus forward Paulo Dybala is close to a move to Tottenham for €70m.

08.00 BST: Arsenal are on the verge of signing Chelsea's David Luiz, says the BBC.

Even though Chelsea are in the middle of a transfer embargo and can't sign a replacement, the two clubs have agreed a fee of £8m which will see Luiz sign a two-year deal to reunite with Unai Emery -- his former manager at PSG.

07.46 BST: Bayern Munich's hopes of signing Manchester City's Leroy Sane may have been ended by injury, according to reports in Germany and the UK.

Sane has been a target for Bundesliga champions Bayern all summer, although City's asking price of £135m has been prohibitive.

Even so, a deal still appeared possible as both clubs would not totally break off contact, but the 23-year-old Germany international suffered a knee injury in Sunday's Community Shield against Liverpool at Wembley.

According to German daily Bild and British paper the Daily Mail, the injury could be worse than initially feared amid concerns that Sane may have suffered anterior cruciate ligament damage.

That would rule him out for much of this season, and scupper any potential transfer for a year.

07.00 BST: Celtic and Arsenal have agreed a Scottish transfer record fee of £25 million for Scotland left-back Kieran Tierney, the BBC reports.

The player is set to travel south ahead of Thursday's Premier League transfer window deadline to complete the deal.

06.47 BST: What the latest on Neymar? Well, he's still at Paris Saint-Germain. BUT, there have been reports that Real Madrid could use Luka Modric as a makweight in a deal to lure the Brazil star to Spain.

06.02 BST: Leeds United full-back Tom Pearce is booked to have a medical at Wigan on Thursday morning, that's according to Phil Hay at the Athletic.

05.56 BST: More on Brian Rodriguez's move from Penarol to MLS pace-setters LAFC. Reports had put Rodriguez's transfer fee at $11.5m, but a source with knowledge of the deal has told ESPN FC that the transfer fee was "closer to $8m."

05.37 BST: Philippe Coutinho's chances of returning to the Premier League this transfer window appear slim. Barcelona head coach Ernesto Valverde confirmed as much late on Wednesday night in the U.S., telling reporters: "Of course I am counting on him. We don't know what's going to happen, but he's with us."

05.23 BST: BBC's David Ornstein says that Ryan Sessegnon's move to Tottenham is a done deal. Spurs will reportedly pay £25m plus Josh Onomah to land the Fulham starlet.

03.49 BST: Speaking of Lukaku, Fabrizio Romano has posted a video of the striker arriving in Italy. It's fair to say that the Inter fans are pleased to see him...

PAPER ROUND (By James Capps)

Spurs set to seal Lo Celso deal

Reports in the Guardian claim Tottenham Hotspur have agreed a €60 million fee with Real Betis for midfielder Giovani Lo Celso, with a deal expected to be finalised before the transfer deadline.

With moves for Philippe Coutinho and Paulo Dybala reportedly hitting trouble, talks with the 23-year-old are set to go smoothly on Thursday, after the Argentine was withdrawn from his side's preseason friendly squad on Wednesday evening.

Lo Celso had only joined Betis on a permanent basis in April after enjoying a fruitful season-long loan spell from Paris Saint-Germain, scoring 16 goals in 45 games for Los Verdiblancos.

The Argentina international will be the second major addition to the Spurs midfield this summer, following the £54m acquisition of Frenchman Tanguy Ndombele from Lyon at the start of July.

PSG keen on Milan's Donnarumma

Paris Saint-Germain are plotting a move for AC Milan goalkeeper Gianluigi Donnarumma, according to reports at Calciomercato.

After the permanent departure of Kevin Trapp to Eintracht Frankfurt, Paris sporting director Leonardo is back in the market for a new shot-stopper, with the Brazilian said to be unconvinced by his most senior keeper, Alphonse Areola.

In fact, the Italian publication claims PSG offered Areola as a makeweight in a player-plus-cash deal for Donnarumma, but that offer was rejected by the Rossoneri.

There are several other obstacles in the French giants' way, with the youngster believed to be reluctant to make the move, while senior members of the Milan board are also said to be strongly opposed to another sale of an academy product, following Patrick Cutrone's move to Wolves.
