Which club has spent most money in the transfer window? Updated figures for 2025 after Isak closes out summer

The summer transfer window is always a flurry of activity, but the 2025 offseason teemed with life as clubs looked to position themselves for competitive action in the coming season.

Thanks to the Club World Cup, there was additional transfer business as those participating in the summer tournament were allowed additional leeway when it came to signing players. Thus, clubs like Chelsea took the opportunity to bring in players in the middle of the competition, as new signing Joao Pedro came on and scored in both the semifinal and final.

Business then continued as usual until deadline day. for most leagues on Monday, September 1.

The Sporting News has a roundup of which clubs were he most active, both in buying players and selling to bolster their finances.

Which club has spent most money in the transfer window?

Highest total spend

With the transfer window officially shut, Liverpool blew every other club out of the water in transfer expenditure this summer, setting the Premier League transfer record not once but twice. Their big-money signings of Florian Wirtz and Alexander Isak were buoyed by other expensive arrivals of Hugo Ekitike, Milos Kerkez, Jeremie Frimpong, and Giovanni Leoni.

Chelsea and Arsenal jockeyed for positioning below the Reds throughout the transfer window, with Newcastle also appearing thanks to a swoop for Nick Woltemade to replace Isak up front.

Enzo Maresca's world champions continued their flurry of transfer activity under the current ownership. Alejandro Garnacho's move from Manchester United to Stamford Bridge took them over a €300m for the window.

Arsenal's deals for Viktor Gyokeres and Cristhian Mosquera moved them into the mix, along with Manchester United whose move for Benjamin Sesko was added to additions of Matheus Cunha and Bryan Mbeumo. 

The list is unsurprisingly dominated by Premier League clubs, who simply have greater financial might than the majority of teams elsewhere, although Real Madrid have also been busy so far and are lurking on the fringes of the top five biggest spenders.

Highest net spend

When it comes to net spend — total expenditure minus income from player sales — Liverpool's outgoing deals managed to offset some of the exorbitant cost of their incoming business this window. Luis Diaz joined Bayern Munich, following Jarell Quansah to the Bundesliga after the defender signed for Bayer Leverkusen. Darwin Nunez moved to Al Hilal in the Saudi Pro League.

Arsenal are the ones who finish atop the list thanks to deals for Gyokeres, Mosquera and Noni Madueke, with only around €10m recouped through sales. Their North London rivals Tottenham Hotspur are fourth behind Manchester United, with a number of additions brought aboard even as they missed out on Eberechi Eze who joined the Gunners.

United's move for Benjamin Sesko, coupled with other major attacking additions, have them near the top, but the Red Devils did significant outgoing business on deadline day to offset some of that spend.

Real Madrid have also had a lack of outgoing moves. The arrivals of defenders Dean Huijsen and Trent Alexander-Arnold in particular were both heralded as early successes after their Club World Cup performances, but big-money departures have not happened. Club great Luka Modric joined AC Milan on a free transfer.

Chelsea might have spent a fortune as detailed above, but significant transfers out of Stamford Bridge have helped to balance things a bit.

Which club has received the most money this transfer window?

Chelsea broke a Premier League record for most money banked from transfer sales, as they were the first side to eclipse the £300 million mark in one transfer window.

While the Blues are the leaders this summer for total income, they were not the winners in the net spend category. That belongs to French side AS Monaco, whose deadline day firesale vaulted them to the top of the list. The club offloaded Breel Embolo, Eliesse Ben Seghir, Wilfried Singo, and Soungoutou Magassa all in the final days of the transfer window, banking a huge amount of cash amid little expenditure.

Bournemouth are in exceptional financial shape after the sales of Dean Huijsen, Milos Kerkez, and Ilya Zabarnyi to bolster their coffers. The paltry business done by Nice and Brighton have them near the top of the net income category as they registered a strong positive number in the books this summer.
