The 2025/26 summer transfer window is already shaping up to be one of the most thrilling in recent years, packed with headline-grabbing moves and staggering transfer fees. With major European clubs in a race to reinforce their squads, the transfer market is buzzing with activity — from emerging starlets moving to elite destinations to high-profile names changing allegiances for eye-watering sums.

Here’s a comprehensive look at the most expensive done deals of the 2025 summer transfer window as of June 12, 2025. From record signings to under-the-radar coups, this detailed list covers the top 17 deals so far.

17. Arthur Vermeeren

Club: Atlético Madrid → RB Leipzig
Fee: €20 million

Belgium's Arthur Vermeeren is one of the most technically gifted midfielders of his generation. Leipzig swooped in for the 20-year-old dynamo who had previously impressed with Royal Antwerp before moving to Atlético. Known for his composure, tactical intelligence, and progressive passing, Vermeeren fits the Bundesliga club’s youth-first model perfectly. Expect him to be a long-term engine in Leipzig’s midfield.

16. Dário Essugo

Club: Sporting CP → Chelsea
Fee: €22.27 million

Chelsea continue their youth revolution with the signing of 20-year-old Dário Essugo. A combative midfielder who broke into Sporting’s first team as a teenager, Essugo brings a mix of energy, versatility, and Portuguese flair. With Enzo Fernández and Moisés Caicedo struggling for consistency, Essugo could see more minutes than expected under Enzo Maresca.

15. Enzo Le Fée

Club: AS Roma → Sunderland
Fee: €23 million

One of the more surprising moves of the summer. After a brief spell at Roma, Le Fée joins newly promoted Premier League side Sunderland. The French midfielder brings creativity, set-piece expertise, and Ligue 1 experience. His signing marks a statement of intent from the Black Cats, who aim to establish themselves as more than just relegation survivors.

14. Luis Henrique

Club: Marseille → Inter Milan
Fee: €23 million

Inter strengthen their flanks with the explosive Brazilian winger Luis Henrique. After shining in Ligue 1, the 23-year-old’s dribbling prowess and attacking directness made him a target for several European clubs. At Inter, Henrique is expected to thrive in a 3-5-2 system, playing as a wide forward or wing-back depending on Simone Inzaghi’s setup.

13. Kevin Danso

Club: Lens → Tottenham Hotspur
Fee: €25 million

Spurs' defensive issues have been well-documented, and the addition of Austrian center-back Kevin Danso could be a solution. Strong, fast, and tactically astute, Danso was a standout for Lens in Ligue 1. His arrival provides much-needed depth and physicality alongside Cristian Romero in the heart of Tottenham's defense.

12. Yan Couto

Club: Manchester City → Borussia Dortmund
Fee: €25 million

After years on loan, Yan Couto departs City to finally establish himself in a starting XI — this time with Borussia Dortmund. The Brazilian full-back blends defensive tenacity with attacking flair and is expected to be a key component in Dortmund’s rebuild following another trophyless campaign.

11. Nico González

Club: Fiorentina → Juventus
Fee: €28.1 million

Juventus continue their domestic raid with the signing of Argentine forward Nico González. After a productive season at Fiorentina, where he scored and assisted freely, González moves to Turin to provide width, goals, and an added layer of unpredictability to Thiago Motta’s new-look Juve.

10. Jobe Bellingham

Club: Sunderland → Borussia Dortmund
Fee: €30.5 million

The Bellingham legacy continues in Dortmund. Following in his brother Jude’s footsteps, Jobe Bellingham makes a major move to the Bundesliga. The 19-year-old midfielder has been exceptional at Sunderland, showing leadership, composure, and creativity beyond his years. Dortmund, masters of nurturing young talent, may have struck gold again.

9. Estêvão

Club: Palmeiras → Chelsea
Fee: €34 million

Brazilian wonderkid Estêvão (also known as “Messinho”) becomes Chelsea’s latest teenage acquisition from South America. The 17-year-old dazzled in Brazil with his flair, footwork, and fearless attacking style. Though unlikely to feature heavily this season, Chelsea are betting big on his long-term potential.

8. Liam Delap

Club: Ipswich Town → Chelsea
Fee: €35.5 million

After a stellar Championship campaign with Ipswich Town, Liam Delap finally earns his Premier League breakthrough. The powerful English striker joins Chelsea in a move that’s raised eyebrows given the fee, but with physical presence and a lethal right foot, Delap might be just what Chelsea need up front.

7. Rayan Cherki

Club: Olympique Lyonnais → Manchester City
Fee: €36.5 million

Pep Guardiola’s squad gains more technical magic with Rayan Cherki. The 21-year-old French attacker is known for his outrageous dribbling skills and flair. His versatility makes him an ideal option across City’s front line, though he will need to improve consistency to truly thrive under Guardiola’s demanding system.

6. Rayan Aït-Nouri

Club: Wolves → Manchester City
Fee: €36.8 million

Aït-Nouri becomes yet another full-back addition to City, who continue their policy of stacking elite depth. His ability to invert into midfield and contribute to build-up play aligns perfectly with City’s tactical identity. A direct upgrade and a smart signing for a side chasing multiple trophies.

5. Jeremie Frimpong

Club: Bayer Leverkusen → Liverpool
Fee: €40 million

Frimpong’s attacking brilliance at Leverkusen made him a hot property. Liverpool, under Arne Slot, look to modernize their wing-play, and Frimpong is a perfect fit. Lightning-fast and endlessly energetic, he could become a game-changer at Anfield, especially if deployed as an advanced wing-back in a new system.

4. Jean-Clair Todibo

Club: OGC Nice → West Ham United
Fee: €40 million

West Ham splurge to secure French defender Jean-Clair Todibo. Highly rated across Europe, Todibo offers pace, physicality, and composure on the ball. With the Hammers aiming for European qualification, Todibo could be the defensive linchpin they’ve lacked since the departure of Declan Rice.

3. Tijjani Reijnders

Club: AC Milan → Manchester City
Fee: €55 million

In another bold midfield move, City grab Dutch international Tijjani Reijnders. After a standout season at Milan, where he dictated tempo and progressed play with elegant precision, Reijnders will slot seamlessly into Pep Guardiola’s system. He may be the long-term successor to Ilkay Gündogan in terms of profile.

2. Dean Huijsen

Club: Bournemouth → Real Madrid
Fee: €59.5 million

One of the more surprising deals this summer, Real Madrid acquire 20-year-old Dutch defender Dean Huijsen from Bournemouth. After a breakout season on the South Coast, Huijsen showed elite-level composure, strength, and aerial dominance. With the likes of Nacho and Rudiger aging, Madrid invest in the future of their backline.

1. Matheus Cunha

Club: Wolves → Manchester United
Fee: €74 million

The most expensive transfer of the 2025/26 summer window so far is Brazilian forward Matheus Cunha joining Manchester United. With 12 goals and 7 assists last season at Wolves, Cunha caught the eye with his link-up play and finishing. United, in desperate need of attacking firepower, believe he can be the centerpiece in Erik ten Hag’s evolving system. Though the fee raised some eyebrows, the Red Devils are betting on proven Premier League output — and Cunha delivers just that.
