This has been an unusual transfer window – in that there have been two windows.

The first opened between Sunday, 1 June and Tuesday, 10 June, because of an exceptional registration period relating to the Fifa Club World Cup.

A total of £400m was spent before the traditional transfer window opened, with Manchester City paying about £108m to sign Rayan Cherki, Rayan Ait-Nouri and Tijjani Reijnders.

It then reopened on Monday, 16 June and will close again on Monday, 1 September.

Six clubs have broken their transfer records this summer.

Brentford completed a deal of up to £42.5m to sign Burkina Faso forward Dango Ouattara from Bournemouth, who spent £34.6m on French centre-back Bafode Diakite.

Newly promoted Burnley and Sunderland have paid £25m and £26m respectively for French midfielder Lesley Ugochukwu and Senegal midfielder Habib Diarra, whose deal could rise to £30m with add-ons.

Nottingham Forest have broken their transfer record twice this summer, first for Switzerland winger Dan Ndoye from Bologna, then winger Omari Hutchison from Ipswich for £37.5m.

In June, Liverpool signed Wirtz from Bayer Leverkusen for a guaranteed £100m and a further £16m in add-ons.

Should those add-ons be achieved, Wirtz’s move to Anfield would become a British transfer record to beat the £107m Chelsea paid Benfica for Argentina midfielder Enzo Fernandez in 2023.

Of the current 20 Premier League clubs, 16 have broken their transfer record in the past four years, with four – Chelsea, Liverpool, Manchester City and Arsenal – having transfer records of £100m or more.

At the other end of the scale, Burnley’s record transfer fee paid is £25m.

Despite spending about £200m on players this summer, Manchester United’s record signing remains Paul Pogba from Juventus for £91m in 2016, around the same time Crystal Palace paid Liverpool £27m for Christian Benteke, which also remains a record for the Eagles.
