Money talks in football, and this summer it is shouting. We have crunched the numbers on every confirmed deal across Europe's top five leagues and the Saudi Pro League to bring you the definitive spending rankings. Net spend included because gross spend without context is just PR.
The Top 10 Biggest Spenders (Gross)
1. Real Madrid — €150M
One player, one hundred and fifty million euros. When you sign Kylian Mbappé, you do not need to shop anywhere else. Madrid's net spend is identical (€150M) because they have not sold anyone significant. Florentino Pérez has been saving up for exactly this moment since 2021. Incoming: Mbappé (€150M).
2. Chelsea — €132M
Different year, same Chelsea. They have already signed Tosin Adarabioyo (free), Kiernan Dewsbury-Hall (£30M), and are closing on Osimhen. Their net spend sits at €95M after selling Conor Gallagher (£35M to Spurs) and Ian Maatsen (£37M to Dortmund). The Clearlake strategy remains: buy everyone under 25 and figure out the XI later.
3. Bayern Munich — €118M
Michael Olise (£50M) is the headline, but Bayern have also spent on defensive reinforcements. Net spend of €72M after offloading a few squad players. The interesting question is whether they will reinvest if Musiala leaves — that £120M would rocket them straight back to number one.
4. Paris Saint-Germain — €105M
Post-Mbappé rebuild is underway. PSG have spread their money across multiple positions rather than one galactico — a genuine strategy shift under Luis Enrique. Net spend of €75M. Watch for that Rashford bid to push them higher up the list.
5. Manchester United — €98M
Branthwaite (£45M) is their biggest outlay so far. INEOS are trying to be more disciplined than the Glazer era and it shows — they are negotiating harder and walking away from deals that do not make financial sense. Net spend of €78M. Still need a striker and a midfielder.
6. Al-Ittihad — €95M
The Saudi champions are not messing around. Richarlison (£50M) is their marquee signing, backed by two other eight-figure deals. Their net spend is €82M. The Saudi window stays open until September 15, so expect more movement.
7. Arsenal — €87M
Arsenal have been relatively quiet by their standards. They have signed a left-back, a midfielder, and are hunting for a striker (hello, Šeško). Net spend of €65M. Edu is being patient, which Arsenal fans find deeply unsettling.
8. West Ham United — €82M
Kilman (£40M) and a new striker are driving West Ham's spending. They are acting like a club that is genuinely trying to break into the top six, not just survive. Net spend of €70M. Fair play to David Sullivan — he is backing Lopetegui properly.
9. Juventus — €78M
Douglas Luiz (€45M) is the main event. Juve are rebuilding under Thiago Motta and spending with purpose. Net spend of €52M after a couple of academy sales. This Juve project is genuinely interesting — they might actually play football this season.
10. Barcelona — €65M
Yes, Barcelona are in the top 10 despite being "broke." The magic of accounting. Their net spend is technically €15M because they have been creative with sales (hello, another economic lever). Nico Williams would double this number if the deal goes through. La Liga's salary cap is the only thing holding them back.
League Spending Comparison
Premier League clubs account for 6 of the top 10 spots. Total Premier League spending so far: approximately €620M. La Liga follows at €280M (mostly Madrid), then Bundesliga at €210M. The financial gap between the Premier League and everyone else is not closing — it is widening. And with the new Champions League format bringing in even more revenue, expect the gap to become a chasm by 2028.
