The 2025 summer transfer window was a busy period, witnessing some of the biggest and most expensive transfers of all time. The 2025 summer transfer window opened early, between Sunday 1 June and Tuesday 10 June, due to the FIFA Club World Cup. FIFA gave member associations with clubs in the tournament the right to apply for an additional registration period.
The Premier League reopened its window again on 16 June, with the rest of Europe’s top leagues following, as usual, on 1 July. Since these dates, deals could be agreed between clubs to improve finances and strengthen squads.
What is Transfer Deadline Day and when does the transfer window end?
The transfer deadline day marks the final opportunity for clubs to sign players and strengthen squads in their respective leagues. It marks the closing of the transfer window.
The summer 2025 transfer window will shut on 1 September, one day later than usual, as 31 August falls on a Sunday. However, the timings at which each league will close its transfer window slightly differ.
- Premier League: 1 September, 7:00 pm BST/ 2:00 pm ET/ 11:30 pm IST
- LaLiga: 1 September, 10:59 pm BST/ 5:59 pm ET/ 3:29 am IST (2 September)
- Serie A: 1 September, 7:00 pm BST/ 2:00 pm ET/ 11:30 pm IST
- Bundesliga: 1 September, 7:00 pm BST/ 2:00 pm ET/ 11:30 pm IST
- Ligue 1: 1 September, 7:00 pm BST/ 2:00 pm ET/ 11:30 pm IST
Potential deals to monitor on transfer deadline day
1. Marc Guehi to Liverpool

- Current Club: Crystal Palace
- Position: Centre-back
- Potential Transfer Fee: £35m
Liverpool are working on a deal with Crystal Palace to sign their skipper ahead of the transfer deadline. Guehi has been pivotal in Crystal Palace’s success in the last couple of years and even earned a spot in England’s Euros squad. He could add plenty of depth at defence and be Van Dijk’s successor at Liverpool.
2. Emiliano Martinez to Manchester United

- Current Club: Aston Villa
- Position: Goalkeeper
- Potential Transfer Fee: £40 million
Manchester United have rekindled interest in the World Cup-winning Emiliano Martinez to solve their goalkeeper issues. Emi Martinez was left out of Unai Emery’s squad this weekend following speculation of a move. The Argentine is high on Manchester United’s radar following a shaky start to the season by Altay Bayindir and Andre Onana.
3. Senne Lammens to Manchester United/Aston Villa

- Current Club: Royal Antwerp
- Position: Goalkeeper
- Potential Transfer Fee: £25 million
Similar to Emiliano Martinez, Senne Lammens is another name on Manchester United’s transfer list. The 23-year-old currently plays for Belgium side Royal Antwerp and has long since agreed personal terms with the club.
Should a move to Manchester United fail to materialize due to the two clubs failing to reach an agreement, Lammens may join Aston Villa. The Belgium goalkeeper could be Emiliano Martinez’s replacement in goal, with a deal worth upwards of £20 million
4. Yoane Wissa to Newcastle United

- Current Club: Brentford
- Position: Striker
- Potential Transfer Fee: £60 million
Newcastle United have struck a record Premier League deal with Liverpool worth £130 million for the transfer of Alexander Isak. Yoane Wissa has scored 19 goals in 35 appearances last season, hence Newcastle’s relentless pursuit of his abilities. Wissa, similar to Isak, has called out his employers, fracturing the relationship between him and Brentford. Brentford may now accept a deal closer to £ 60 million.
5. Randal Kolo Muani to Juventus

- Current Club: PSG
- Position: Striker
- Potential Transfer Fee: £51 million
PSG and Juventus have been in negotiations over the transfer of the French striker for over three months, with Kolo Muani’s heart set on Juventus. Kolo Muani enjoyed a successful spell with the Italian giants, scoring 10 goals for them.
However, reports from many reputed journalists suggest that talks are off between the two clubs right now. Kolo Muani serves as a top option for various top clubs, and the likes of Tottenham and Chelsea are reportedly interested.
Conclusion
As the clock ticks down on Deadline Day 2025, clubs across Europe are making their final moves to strengthen squads before the window slams shut. The deadline day promises all the drama and unpredictability that football fans have come to expect, with last minute negotiations, surprise exits, and unexpected arrivals still on the cards. The closing hours of the summer transfer window are set to provide a fitting conclusion to another action packed transfer season.
