Everton have signed centre-back Jake O’Brien from Lyon on a four-year deal for £16.4m.
The 23-year-old Republic of Ireland defender made 27 appearances for the Ligue 1 side last season.
He becomes Everton’s fifth summer signing after midfielder Tim Iroegbunam, forwards Iliman Ndiaye and Jesper Lindstrom, and the return of Jack Harrison on loan from Leeds.
“I’m buzzing and so happy to have signed,” O’Brien said.
“I’ve been dreaming of this kind of move in the Premier League, with such a historic club. It’s a very exciting move for me.”
O’Brien said Everton was a “huge club” with a “big future”.
O’Brien began his career with hometown club Cork City, then joined Crystal Palace’s academy on loan before signing for the Premier League club permanently.
