Barcelona forward Ousmane Dembele must leave the club before the January transfer window closes for both his sake as well as the Catalan club to ensure they get a fee as his contract ends in June, club director Mateu Alemany has said.

Dembele, who joined Barcelona from Borussia Dortmund in 2017, has failed to deliver on his potential that made the Spanish club pay 105 million euros ($119.11 million) for his services, scoring only 31 goals in 129 appearances.
