Relegated teams will fight to keep hold of their top talents - or at least recoup a sizeable fee for them - while promoted teams endeavour to bring in notable names in a bid to retain their new-found second-tier status.

Biggest deals of the 2026 Championship summer transfer window

Following West Ham United's relegation from the Premier League, rumours have swirled surrounding one player in particular - Portuguese midfielder Mateus Fernandes.

The former Southampton starlet was a standout performer in an otherwise dismal campaign for the Irons, earning his stars as a number six, number eight and number 10 at the London Stadium.

Manchester United and Arsenal are both believed to have taken a serious interest in Fernandes, but the Red Devils are supposedly at the head of the queue for the midfielder, who has an £80m price tag on his head.

Fernandes's Irons teammate Jarrod Bowen is also facing an uncertain future, although he has plenty of time to ponder his next move after being left out of England's squad for the 2026 World Cup.

Newcastle United, Liverpool, Chelsea and Manchester United have all been touted as viable destinations for the 29-year-old, but there have not yet been any concrete developments.

A handful of transactions have already gone through, including Southampton's permanent signing of goalkeeper Daniel Peretz, and the arrival of South American midfielder Jhon Solis at Birmingham City.
