Barcelona midfielder Ousmane Dembele has had successful surgery after dislocating a knee tendon playing for France at the Euros and will return to action in four months, the Catalan club said on Monday.

"Ousmane Dembele was successfully operated on in Turku (Finland) by Doctor Lasse Lempainen under the supervision of the club's medical services," Barca said in a statement, adding he would return to training in four months' time.

He suffered a dislocated biceps tendon in his right knee after coming on as a substitute in France's 1-1 draw with Hungary last week

With 27 caps under his belt, Dembele had been hoping to feature regularly at the Euros after scoring in a pre-tournament win over Wales but came off the bench in both their opening win over Germany and then against the Hungarians.

The winger, who scored 11 goals in 44 appearances for Barcelona last season, had suffered a previous injury in February last year when he tore a hamstring.

Dembele joined Barcelona in September 2017 for 135 million euros ($161 million) from Borussia Dortmund.
