Aston Villa have completed the signing of midfielder Morgan Sanson from Marseille for a fee reportedly in the region of £15.5million.
The 26-year-old has signed a four-and-a-half year deal at Villa Park, which is subject to international clearance.
Villa boss Dean Smith told his club's official website: "Morgan has performed consistently at the highest level in French football for a number of seasons as well as in this season's Champions League, and is a player with the quality and experience to play in any midfield position.
"He will add real competition for starting places and gives us more squad depth which is vital to competing successfully in the Premier League."
Marseille boss Andre Villas-Boas left Sanson out of the squad to face Monaco on Saturday due to an expectation that the transfer would be completed.
Sanson joined Marseille from Montpellier in 2017 and scored 22 goals in 120 appearances for the club, featuring in the 2018 Europa League final against Atletico Madrid.
