Atletico Madrid have signed Moussa Dembele on loan from Lyon until the end of the season.
Lyon said in a statement that the loan deal worth €1.5m (£1.3m) is accompanied by a purchase option set at €33.5m (£27m).
On top of that there may be added incentives up to €5m (£4.5m), as well as a sell-on fee of 10 per cent on a possible future transfer.
The 24-year-old joined Lyon from Celtic for €22m (£20m) in August 2018 and is under contract until June 2023.
He has scored 45 goals in 108 games for the Ligue 1 leaders.
Lyon have signed Leicester striker Islam Slimani to replace him.
Slimani, 32, has signed an 18-month contract at Lyon after the Ligue 1 club agreed the loan of former Fulham and Celtic forward Dembele to Atletico.
The Algerian international joined Leicester from Sporting Lisbon in August 2016 for a club-record £29m fee.
Slimani made one Leicester appearance this season, coming on as a substitute in October's 1-0 Premier League home defeat to Aston Villa.
