However, Galatasaray made headlines by breaking into the top 10 with the blockbuster signing of Victor Osimhen.

Top 10 expensive signings in the 2025 summer transfer window

10. Luis Diaz – €70M

Luis Díaz made a high-profile move from Liverpool to Bayern Munich for €70 million—a fee fitting for an experienced and proven talent in European football. The versatile forward was eager for a fresh challenge, and it didn’t take him long to settle in. He hit the ground running, scoring in the Supercup and quickly making his mark as he began an exciting new chapter in his career.

9. Martin Zubimendi – €70M

Arsenal had been tracking Martin Zubimendi for quite some time, with the midfielder high on their wishlist. After months of planning, they finally secured his signature from Real Sociedad in the summer transfer window for €70 million. The move came as part of the club’s efforts to replace Thomas Partey, and Zubimendi was identified as the ideal successor in the heart of midfield.

8. Maethus Cunha – €74M

Matheus Cunha has completed a €74 million move from Wolverhampton Wanderers to Manchester United. While the price tag raised some eyebrows among market watchers, the transfer reflects the growing excitement around Cunha's technical ability and knack for making an impact in key moments. Now at Old Trafford, he begins an exciting new chapter in his career.

7. Bryan Mbeumo – €75M

After a long and drawn-out transfer saga, Bryan Mbeumo has finally made the switch from Brentford to Manchester United in a deal worth around €75 million. The talented forward wasted no time making an impact, already opening his account in the Premier League for the Red Devils. Known for his sharp attacking instincts and consistency in the Premier League, Mbeumo brings much-needed versatility to United’s frontline — a boost the club will be hoping pays off in their push for silverware.

6. Victor Osimhen – €75M

Nigerian striker Victor Osimhen has completed a €75 million move from Napoli to Galatasaray, becoming the most expensive signing in Turkish football history.

After years of being linked with Premier League clubs—most notably Chelsea—Osimhen's performances had dipped slightly, but he still deserves credit for turning down a big-money offer from the Saudi Pro League to join Galatasaray.

The Turkish giants acted decisively to secure his services permanently, rather than risk losing their star forward next season. Osimhen had already spent the previous campaign on loan at the club, making a strong impression and prompting Galatasaray to make the deal official.

5. Benjamin Sesko – €77M

Manchester United have signed Slovenian forward Benjamin Sesko from RB Leipzig for a base fee of €77 million.

Sesko is seen by United as the long-term replacement for Rasmus Højlund, who has made a surprise move to Napoli. The 22-year-old striker is eager to prove himself at a club that’s pushing to be competitive again.

After missing out on Liam Delap and Viktor Gyökeres, United turned their attention to Šeško. It’s a bold move, especially with proven Premier League talent like Ollie Watkins still on the table, but the club is betting on Sesko’s potential.

4. Nick Woltemade – €85M

In a club-record €85 million deal, German international forward Nick Woltemade made the move from Stuttgart to Newcastle United.

The size of the investment speaks volumes about Newcastle’s ambitions and the potential they see in the young striker. His arrival also paved the way for Alexander Isak’s transfer to Liverpool, with many seeing Woltemade as a direct replacement for the Swedish star.

3. Hugo Ekitike – €95M

French forward Hugo Ekitike became one of Liverpool’s most expensive signings after completing a €95 million move from Eintracht Frankfurt. The deal includes an upfront fee of €95 million, with additional performance-related bonuses.

Ekitike had previously shown glimpses of his potential during spells at Paris Saint-Germain and Eintracht Frankfurt. Now at Anfield, he's already made an impact, scoring two league goals early in the season.

2. Florian Wirtz – €125M

Liverpool spent a whopping €125 million, including add-ons, to sign the German talent Florian Wirtz from Bayer Leverkusen. Fans were buzzing with excitement, expecting the young attacking midfielder to make a huge impact at Anfield.

So far, though, Wirtz’s brief appearances in the last three games haven’t quite lived up to the hype. Despite that, supporters are still hopeful he’ll soon show his true potential—after all, Liverpool invested a huge sum to bring him in, and everyone’s eager to see him reach his peak.

1. Alexander Isak – €144M

Swedish striker Alexander Isak became one of the most expensive signings in British football history when he made the move from Newcastle United to Liverpool for a record-breaking €144 million. The drama of the 2025 summer transfer window reached its peak on deadline day with Isak’s high-profile transfer finally sealed.

With no add-ons involved, the deal effectively feels like a €150 million move, helping Newcastle save on loyalty payments. For Liverpool, signing Isak is a clear statement of intent as they strengthen their attacking options ahead of the new season.
