Bayern Munich have been dealt a huge injury blow, with Arturo Vidal set for an extended spell on the sidelines.

As quoted by Sky Sports, Bayern boss Jupp Heynckes delivered a damning verdict on the experienced midfielder’s condition and confirmed that he will be out for a long period due to a knee problem.

He slipped and went down. I’ve just spoken to (team) doctor (Hans-Wilhelm) Muller-Wohlfahrt on the phone. He’s had an MRI scan. Arturo has a loose body in his knee. That’s preventing him stretching.

He’s already on his way to Augsburg. He needs keyhole surgery on his knee. Arturo will definitely be out of action for a while.

Vidal is extremely likely now to be unavailable for Bayern’s crunch clash with Real Madrid in the Champions League semi-final first leg, which is sure to come as a big blow for Heynckes as he bids to help the team to yet another final in the competition.

Speculation has clouded Vidal’s future at the Allianz Arena but the Chilean international remains a vastly important figure at the Bundesliga side.

Vidal will hope to undergo a successful operation on his knee and will be keen to come back stronger, with Bayern continuing to assert their lasting dominance in the top tier of German football.
