Michael Keane has completed his move to Everton in a deal which could rise to a club record-equalling £30m.
The 24-year-old Burnley defender has signed a five-year deal and becomes the club's fifth summer signing after Jordan Pickford, Davy Klaassen, Henry Onyekuru and Sandro Ramirez, whose move from Malaga was announced earlier on Monday.
Everton announced the news via their official Twitter account, posting: "We've signed Michael Keane on a five-year deal for a fee which could rise to a club-record £30m."
Keane was delighted to have secured his move and the chance to work under Toffees boss Ronald Koeman, a stylish defender with Barcelona and Holland during his own distinguished playing career.
He told the club's official website, www.evertonfc.com: "I'm absolutely delighted to be at Everton, a fantastic football club with passionate fans and a great tradition and I can't wait to come into training tomorrow to meet all the lads.
"First and foremost, the manager was a big factor in me coming to the club. He played in my position when he was a world-class player for a great Barcelona side and a great Dutch side and the style of football he likes to play will suit me, I believe.
"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.
"He's convinced me that he can still improve me in certain areas of my game. I'm only 24 which, for a centre-half in the Premier League, is relatively young. I've still got a long way to go and I know this and hopefully under his guidance I'll keep improving.
"You always want to play for a manager who believes in you. I wanted to come somewhere I was wanted by the staff, players and fans as well. I feel like Everton is the perfect match."

The 21-year-old forward Sandro completed his move to Goodison Park after the Toffees triggered a £5.3m release clause in his contract with the Spanish La Liga side.
He won two La Liga titles with Barcelona before joining Malaga on a free transfer, and scored 16 goals in 31 games for the club last season.
He had been heavily linked with a number of top clubs including Atletico Madrid, whose hopes were dashed when the Court of Arbitration for Sport upheld a transfer ban last month.

Sandro told Everton's official website: "I'm very happy, this is a big step in my career.
"I know I'm signing for a massive club in England. Everton is the ideal place for me, I've got the ideal manager who is going to keep giving me the confidence to improve my game.
"It's a big jump in my career coming to the Premier League and for a club like Everton which is really on the up. They have got big plans and want to succeed and keep developing.
"Everton have made some big signings and we're hoping we can put in a great season and hopefully then we can achieve that aim of getting in the Champions League. It will be a big season for us."
Sandro's signing is another statement of intent by Toffees boss Ronald Koeman, who smashed the club's transfer record to sign goalkeeper Pickford from Sunderland last month.
Koeman said: "There was a lot of interest in Sandro because, of course, he's a goalscorer, he's young and he has a big future in the game.
"We have been trying to bring in good players so we can have greater productivity in the team and he will bring that. He will bring a lot of good qualities and he's a really good goalscorer, too."
