The year is already over for Barcelona's record signing, Ousmane Dembele.

Barcelona confirmed on Sunday that the player will be sidelined for up to four months after rupturing a tendon in Saturday's win at Getafe.

Dembele, 20, will travel to Finland this week to undergo surgery with a specialist.

The France international was making his first ever La Liga start at the Coliseum Alfonso Perez when he was forced off after just 25 minutes.

The Catalan club had initially hoped he had suffered a minor hamstring problem and would only be out for a few weeks, but tests at the club's training ground on Sunday revealed the worst case scenario.

"Tests have confirmed that first team player Ousmane Dembele has ruptured the tendon in his femoral bicep in his left thigh," Barca said in a statement.

"The player will be operated on by Dr. Sakari Orava in Finland this week. He is expected to be out for between three and a half months and four months."

Dembele was brought in as a direct replacement for Neymar but Barcelona would be pained that their huge investment is going down the drain at least for now.
