Aston Villa have signed Lille midfielder Idrissa Gueye on a four-year contract.
Manager Tim Sherwood said the 25-year-old, who has 24 Senegal caps, had been one of the best midfielders in France in the last couple of years.
"I'm really pleased to have brought Idrissa on board," he said.
"He's been one of the best young midfielders in France for the last few seasons and there were a lot of teams trying to sign him this summer.
"I believe we are signing a player who is hungry to succeed, is entering what should be his best years and is perfectly suited to the Premier League."
He is likely to fill a hole in midfield soon to be vacated by captain Fabian Delph, who is on the verge of a move to Manchester City.
Earlier the club confirmed the departure of defender Antonio Luna to Spanish club Eibar.
