Crystal Palace have signed Denmark defender Joachim Andersen on a five-year contract from French club Lyon.
The 25-year-old spent last season on loan at Fulham, whom he captained, which saw the side relegated to the Championship.
He has joined the Premier League side for an undisclosed fee reported to be around £20m.
"I'm extremely proud to be joining Crystal Palace," centre-back Andersen said.
"And to be playing in the world's best football league.
"The management of the club and Patrick Vieira have given me very strong assurance that they know my qualities, they believe in me and want me to play an important role in the team.
