Michael Keane has completed his switch from Burnley to Everton on a five-year deal that could be worth a club-record-equalling fee of £30m.
The 24-year-old was pictured leaving the Toffees' training facility on Monday afternoon after undergoing a medical, and confirmation of the move has now been given by the Toffees.
Everton are said to have beaten off competition from a number of Premier League rivals to land Keane's signature, setting them back an initial fee of £25m that could rise if various add-ons are met.
Manager Ronald Koeman is delighted to have further strengthened his squad, telling Everton's official website: "Michael was high among the players we wanted to bring to Everton this summer and I'm delighted he is here at the club.
"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.
"I believe there is much more to come from Michael and that's what makes his signing really exciting for me - we will see his development as a player along with the progression overall within the Club.
"It's another really positive sign of the direction the Club is moving in. He's 24 years old, his best years are to come, he's an England international, too, and I couldn't be more pleased that he's now a Blue."
It continues Koeman's spending spree ahead of the 2017-18 campaign, with Jordan Pickford, Davy Klaassen, Henry Onyekuru and Sandro Ramirez already joining for a combined £63m.
Former side Manchester United are likely to receive a cut of the transfer, two years after selling him to the Clarets for £2m.
