Bayern Munich have confirmed that Thiago Alcantara will face another lengthy spell on the sidelines after suffering a ligament tear in training.

The 23-year-old returned to training with the Bundesliga champions this week after spending around seven months out of action with an ankle injury.

However, the Spain international has suffered a damaging setback as he prepares to undergo surgery.

Bayern wrote on their Twitter page: "Devastating: @Thiago6 has suffered a ligament tear in training. He needs an operation and is set for another lengthy absence."

Alcantara completed his first full training session on Monday following his initial injury layoff.
