The 20-year-old was injured at the French training camp in Clairfontaine while preparing for Friday's 2018 World Cup qualifier at Paris' Stade de France against Sweden.

Bayern say a medical examination in Munich on Thursday revealed Coman has torn the cruciate ligament in his knee and ruptured the ankle capsule in his left leg.

He is expected to be out for two months.

Coman will miss Bayern's six remaining league games, plus their Champions League clashes at Russia's Rostov on November 23 and at home to Atletico Madrid on December 6, a match likely to decide the winner of Group D.

After missing the first two league games this season with an ankle injury, the French winger has struggled for form and has so far yet to play a full  Bundesliga match.

He has managed only 25 minutes of Bayern's four Champions League games this season.

Bayern play rivals Borussia Dortmund away on November 19, their first match after the winter break.

Carlo Ancelotti's league leaders are set to welcome back Spain defender Javi Martinez.

The 28-year-old has missed the last few weeks with a leg injury and will return to training on Monday.
