Everton have signed Burnley centre-back Michael Keane on a five-year contract.
Keane, 24, moves to Goodison Park as part of a deal that could rise to a club record £30m.
Speaking after the move, Keane said: "I watched a lot of Everton last season and I believe I really suit how the team likes to play.
“I feel like this is a great place to come and continue my development as a player."
"[Everton manager Ronald Koeman] used to play in my position. I have been fortunate enough that in the clubs I have played in the past, the manager has played in my position as well and I feel like he was a very classy centre-half so he can still teach me things," he told Sky Sports.

Koeman revealed that the defender had been one of their priorities.
"Michael was high among the players we wanted to bring to Everton this summer and I'm delighted he is here," said Koeman.
"We knew there would be competition from other clubs but Michael believes in the ambition of Everton and what we want to do and this is the perfect moment for him to come."
The England stopper is the Toffee’s fifth signing of the summer, and the second to arrive on Monday after £5.2m Malaga striker Sandro Ramirez.
Everton have now spent more than £90m, which included another £30m on goalkeeper Jordan Pickford from Sunderland.
