Everton have signed Republic of Ireland central defender Jake O’Brien from Lyon, the Premier League club announced on Tuesday.

The 23-year-old has agreed a four-year deal for an undisclosed fee, although British media reports suggested O’Brien had moved to Merseyside for a figure of around £17 million ($22 million).

O’Brien won his first Ireland cap playing alongside Everton captain Seamus Coleman in a 2-1 win over Hungary in June.

He is the Toffees’ fifth signing of the summer transfer window, following the loan return of Leeds winger Jack Harrison and the arrivals of midfielder Tim Iroegbunam and forwards Iliman Ndiaye and Jesper Lindstrom.

“Seamus has been on to me to sign for Everton,” O’Brien, who left Crystal Palace for France last summer, told his new club’s website. “He’s a top guy, a brilliant captain and to play under him here as well as with Ireland will be a privilege.

“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. When the transfer window opened there were other clubs in for me but there was only one club I wanted to go to – it was Everton. They’ve shown the faith in me so now it’s my turn to show why on the pitch.”
