The summer transfer window across Europe’s top four leagues has officially slammed shut — and while a few minor deals may still trickle in from less prominent leagues, the major business is done. The big names have moved, the record fees are in the books, and the top 10 most expensive transfers of the summer are now set in stone.

On deadline day, in a dramatic late twist, Liverpool pulled off a blockbuster by sealing the signing of Alexander Isak from Newcastle United, instantly catapulting the deal to the top of the list with a jaw-dropping €144 million fee.

Here’s how the Top 10 Most Expensive Transfers of Summer 2025 stack up:

1. Alexander Isak (Newcastle United ➡️ Liverpool) – €144M
A statement signing. The Swedish striker becomes the most expensive player of the window, with Arne Slot clearly betting big on Isak to lead Liverpool’s new attacking era.

2. Florian Wirtz (Bayer Leverkusen ➡️ Liverpool) – €125M
Another major coup for the Reds. The German playmaker has been one of the Bundesliga’s brightest stars, and his move adds flair and vision to Liverpool’s midfield.

3. Hugo Ekitike (Eintracht Frankfurt ➡️ Liverpool) – €95M
Yes, Liverpool again. The French forward completes a stunning triple swoop, making it clear the Merseyside giants are not here to rebuild — they’re here to dominate.

4. Nick Woltemade (Stuttgart ➡️ Newcastle United) – €85M
A surprising move, but Newcastle have high hopes. The towering German forward arrives to fill the void left by Isak’s departure.

5. Benjamin Šeško (RB Leipzig ➡️ Manchester United) – €76.5M
Tall, quick, and lethal — Šeško adds another dimension to United’s attack. This could be one of the most impactful moves of the summer.

6. Victor Osimhen (Napoli ➡️ Galatasaray) – €75M
A jaw-dropping switch. The Nigerian star swaps Serie A for the Süper Lig in a headline-making move that reflects Galatasaray’s European ambitions.

7. Bryan Mbeumo (Brentford ➡️ Manchester United) – €75M
Pacey and versatile, Mbeumo’s addition gives Ruben Amorim even more attacking options. United fans will be watching closely to see how he fits in.

8. Matheus Cunha (Wolves ➡️ Manchester United) – €74.2M
A creative spark with Premier League experience, Cunha could thrive at Old Trafford if given the freedom to roam.

9. Martín Zubimendi (Real Sociedad ➡️ Arsenal) – €70M
Mikel Arteta finally gets his man. The Spanish midfielder brings composure and technical prowess to Arsenal’s engine room.

10. Luis Díaz (Liverpool ➡️ Bayern Munich) – €70M
A sensational departure from Anfield. The Colombian winger joins Bayern, adding even more firepower to the German champions’ wide options.
