What deals have already been done this summer?

In an eye-catching window, Ole Gunnar Solskjaer finally completed a £73m deal for Jadon Sancho from Dortmund, as well as a £34m move for France World Cup winner Raphael Varane from Real Madrid.

Premier League champions City may have missed out on Ronaldo, but broke the British top-flight record on a single player by signing midfielder Jack Grealish from Aston Villa for £100m.

And European champions Chelsea re-signed striker Romelu Lukaku from Serie A champions Inter Milan for a mammoth £97.5m, the second highest deal of the window.

Arsenal have spent about £140m on reinforcements too, including £50m to Brighton for England defender Ben White, £30m on Real Madrid midfielder Martin Odegaard and £24m on goalkeeper Aaron Ramsdale from Sheffield United.

The Gunners have also cut £200,000-a-week off their wage bill as Brazil winger Willian had his contract mutually terminated to seal a return to first club Corinthians.

Liverpool triggered the £36m release clause for defender Ibrahima Konate from RB Leipzig, while Villa spent the Grealish cash on astute acquisitions including striker Danny Ings, midfielder Emiliano Buendia and winger Leon Bailey.

In Europe, Lionel Messi did the unimaginable by leaving Barcelona and joining PSG after his contract ended at the Nou Camp.

That deal alone would have ‘won’ the window for the Ligue 1 side, but they also made eye-catching moves for Italy goalkeeper Gianluigi Donnarumma, Spain defender Sergio Ramos and Netherlands midfielder Georginio Wijnaldum… all on free transfers.
