Premier League transfer window 2025: When does it open? When does it close? A complete guide

With the Club World Cup now over, attentions all across the footballing world will turn towards the transfer window in the few weeks remaining before the start of domestic football in Europe.

The first significant dealings have already been done, as clubs were permitted an extra registration period to complete early signings, and Manchester City were the biggest winners of that window, which ran from June 1 to June 10.

Rayan Cherki, Tijjani Reijnders and Rayan Ait-Nouri all arrived at the Etihad, while Chelsea captured Liam Delap, Liverpool poached Jeremie Frimpong to replace Real Madrid-bound Trent Alexander-Arnold, and Matheus Cunha swapped Wolverhampton Wanderers for Manchester United.

Several significant dealings have already been done in the past couple of weeks too, most notably at Liverpool, where Florian Wirtz and Milos Kerkez have arrived to keep Frimpong company, with Hugo Ekitike set to join them too.

Following the reopening of the transfer window, clubs across the globe are all engaging in moves to bolster their squads ahead of the new season, with the Premier League on course to be the outright biggest spenders yet again, with hundreds of millions already swapping hands in July.

Now that the summer window is in full flow, Sports Mole provides a comprehensive guide to the current transfer market.

When did the 2025 summer transfer window open and when does it close?

After the 'exceptional registration period' shut, teams were granted a five-day pause before the second transfer window opened on Monday, June 16.

That market will run for the duration of the summer as is standard, despite reports earlier this year claiming that clubs would discuss closing the window before the start of the season.

Instead, teams will be free to sign and sell players until Monday, September 1, although there will be a countdown to 7pm rather than 11pm this time around as the window is closing four hours earlier.

However, clubs will be expected to have an additional two hours to complete transfers if they have submitted a deal sheet, meaning that some signings may not be announced until 9pm or later on September 1.

What are the biggest deals that could be done this summer?

The Premier League recently saw its newest £100m+ player arrive, as Liverpool confirmed the signing of former Bayer Leverkusen playmaker Florian Wirtz in a club-record deal on June 20.

The top-flight champions followed up that unprecedented purchase with another marquee addition in the shape of Bournemouth left-back Milos Kerkez, whom they paid £40m for to make him one of their 10 most expensive signings of all time.

Hugo Ekitike will also move into that list once his £79m deal to join from Eintracht Frankfurt goes through, taking Liverpool's summer spending to almost £300m.

All eyes will also be on whether Arsenal can finally add that elusive big-money number nine to their ranks, as the Gunners are closing in on Sporting Lisbon's Viktor Gyokeres, after finally getting a deal for Martin Zubimendi over the line too.

While Cunha's £62.5m move to Manchester United will make many headlines, the biggest transfer stories at Old Trafford should relate to outgoings, as the futures of Kobbie Mainoo, Antony, Jadon Sancho, Marcus Rashford and Alejandro Garnacho are both up in the air.

Bryan Mbeumo is set replace one of them, as his move to Old Trafford is close to completion, choosing the Red Devils over a reunion with Thomas Frank at the Tottenham Hotspur Stadium.

However, all is not lost for Spurs, who have brought in West Ham United's Mohammed Kudus for £55m, having also cooled their interest in Crystal Palace's Eberechi Eze.

Over at Chelsea, the Blues have continued their strategy of signing attacker after attacker by capturing Jamie Bynoe-Gittens and Joao Pedro, which opened the door for Arsenal to sign Noni Madueke for £50m.
