​Bayern Munich have confirmed that midfielder Arturo Vidal will have surgery on the knee injury he ​suffered in training this past Sunday. 

The Chilean, who got injured while trying to catch a stray ball in training, could potentially miss both legs of the Bavarian giants' ​Champions League semi-final against Real Madrid. 

Vidal had to be helped off the training field and left the session on a golf cart, with coach Jupp Heynckes confirming earlier today that he will be undergoing keyhole surgery. He will miss their DFB Pokal semi-final against Bayer Leverkusen on Tuesday.

The club's twitter account posted, "He tripped without any contact from anyone else. Arturo has a loose body in his knee. He needs a small procedure and will be out for the time being. He's a fighter. I'm confident for his recovery"

The combative midfielder is an important member of the Bayern squad and would have definitely been in Heynckes' plans for the semi-final against Real. He was ​sent off when the two sides met in the quarter-finals in last season's competition. 

The German side have been in tremendous form ever since their 72-year-old former coach took over, winning almost every match across all competitions. They have already sealed the Bundesliga title and look set to go all the way in the DFB Pokal as well. 

With just over a week left for the first leg of their Champions League semi-final at the Allianz Stadium, Bayern Munich would be hoping that Arturo Vidal recovers in time to bring his aggression and competitive edge to the table against Real Madrid.
