Barcelona have confirmed that winger Ousmane Dembele will be sidelined for six months following surgery on a serious hamstring tear.
He was on his way back to full fitness following another thigh injury when he pulled out of training last week.
The 22-year-old has suffered several injuries – in both legs – since joining the La Liga champions from Dortmund in 2017.
He has played only three full games this season, missing 63 games in all competitions at Barca through injury.
Dembele, a member of France’s World Cup-winning squad, is expected to miss Euro 2020.
