Everton have confirmed the arrival of Norwich City centre-back Ben Godfrey on a five-year deal.
The fee for the 22-year-old is undisclosed but is believed to be in the region of £25m, potentially rising to £30m.
Godfrey played an integral part in Norwich's promotion to the Premier League in 2018-19 and captained England Under-21s on his full debut in September 2019.
The York City academy product becomes the Toffees' fifth major signing of the window, following the arrivals of Niels Nkounkou, Allan, Abdoulaye Doucoure and James Rodriguez.
Speaking after completing his move to Goodison Park on deadline day, Godfrey told his new side's official website: "I am most looking forward to being part of a massive club.
"I have been on an upwards journey and now I have taken the step of making the move to Everton. It is great and it is an honour.
"You want to be part of a huge club like Everton. It is a club full of history. It has world-class players, some young players.
"I have senior players who will help me kick on to the next level. I am looking forward to working with them and, hopefully, having a successful time at this club."
Everton have made a perfect start to their campaign, winning seven games from seven in all competitions.
