Manchester City have completed the signing of Jeremy Doku from Rennes on a five-year deal.
City had agreed a fee of €65million (£55.5m) with Rennes for Doku.
City winger Riyad Mahrez left earlier this summer before Kevin De Bruyne suffered a hamstring injury that could see him ruled out until next year.
Following Mahrez’s exit, Bernardo Silva and Cole Palmer have stepped in so far this season, while Phil Foden put in a man-of-the-match performance from a similar position in Saturday’s Premier League victory over Newcastle United.
Doku said: “This is a great day for me, both personally and professionally. Manchester City are the best team in world football, so to be joining them is something very special for me and my family.
“I am a young player with so much learning and improving to do. Working with Pep and his staff, and playing alongside these world-class players, will make me a much better player. I feel sure of that.”
Doku made 35 appearances for Rennes last season, scoring six goals. He will wear the No 11 shirt at City.
City are next in action this Sunday away to Sheffield United.
