The 2025 summer transfer window has seen unusual activity, largely influenced by the new FIFA Club World Cup format. This led many European clubs to accelerate their dealings, with a special transfer period in early June preceding the official July 1 start. Major clubs aimed to finalize deals before pre-season, resulting in several high-value signings already occurring in June. Some transfers, like Arsenal`s potential acquisition of Viktor Gyokeres from Sporting CP, are still pending. Below, we examine the five most expensive transfers completed so far this summer, according to Transfermarkt:
5. Mohammed Kudus, Tottenham (€64 million)
Tottenham, aiming to rebound from a disappointing 17th-place Premier League finish (despite winning the UEFA Europa League against Manchester United), is revamping its squad. With Champions League football ahead under coach Thomas Frank, Spurs have already secured defender Kevin Danso from Lens and made Mathys Tel`s move from Bayern Munich permanent. Their most significant signing, however, is Mohammed Kudus from West Ham for approximately €64 million, positioning him as Tottenham`s second-most expensive transfer ever, only behind Dominic Solanke.
4. Jamie Gittens, Chelsea (€64.5 million)
Fresh off their UEFA Conference League triumph and historic win in the inaugural FIFA Club World Cup (new format), Chelsea is actively bolstering its squad for the upcoming season. Alongside securing Brazilian prodigy Estevao from Palmeiras, the Blues have brought in striker Liam Delap from Ipswich, Joao Pedro from Brighton for €63 million, and Jamie Gittens from Borussia Dortmund for roughly €64.5 million. Gittens` transfer now places him among Chelsea`s top ten most expensive signings, surpassing Christian Pulisic.
3. Martin Zubimendi, Arsenal (€70 million)
Arsenal has been exceptionally busy in the transfer market this summer, following former Atletico Madrid sporting director Andrea Berta`s appointment to oversee their recruitment. Among their key acquisitions, and with Viktor Gyokeres potentially joining as another significant signing, the Gunners have secured midfielder Martin Zubimendi from Real Sociedad for €70 million. Zubimendi arrived at Arsenal this summer, alongside goalkeeper Kepa Arrizabalaga from Chelsea and midfielder Christian Norgaard from Brentford.
2. Matheus Cunha, Manchester United (€75 million)
Manchester United consistently feature prominently in transfer discussions. Despite a disappointing season that culminated in a Europa League final loss to Tottenham, Ruben Amorim`s squad is actively pursuing new players amidst the club`s financial constraints. The Red Devils have already completed the signing of Matheus Cunha from Wolverhampton for approximately €75 million, marking him as the second-most expensive transfer this summer to date.
1. Florian Wirtz, Liverpool (€125 million)
Liverpool has executed the most significant transfer of the summer to date, acquiring former Bayer Leverkusen standout Florian Wirtz for a club-record fee of €125 million. This makes him the most expensive signing in the club`s history. Wirtz is set to join the reigning 2024-25 Premier League champions ahead of the new season, arriving with immense expectations after years of stellar performances in Germany. Could this be the signing that propels the Reds to UEFA Champions League glory?
