Bayern Munich announced Wednesday that top scorer Robert Lewandowski will be out of action for nearly four weeks, after suffering a severe injury to his left knee during the match against Chelsea, Tuesday in the first leg of the Champions League final in football.

The Bavarian club said in a statement posted on its website, that Lewandowski, who had fought a full Tuesday meeting, "suffered a fracture in the left knee joint during the 3-0 victory over Chelsea," which requires him to be put in gypsum ten days before the rehabilitation process begins.

He explained that this would lead to "the absence of the striker for about four weeks", and that the diagnosis is the result of tests he underwent after the team returned from London.

It is feared that the absence of the striker, 31-year-old, will have a negative impact on the Bavarian club, especially since it offers an impressive offensive performance this season, scoring 39 goals in 33 games in various competitions.

The last of these goals came against Chelsea, when he scored the third goal for his team about a quarter of an hour before the end of the original time of the game, after he had himself granted the two decisive passes, after which his teammate Serge Gnabry scored the first two goals at Stamford Bridge.

As a result of Tuesday's match, Bayern moved ahead in the quarter-finals of the continental competition in which he is looking for his first title since 2013. He hopes that Lewandowski's recovery from his injury will not last long, given that the next round of the Champions League kicks off in the first week of April.

Bayern will play the second leg against Chelsea on March 18.

On the local level, Lewandowski’s absence comes at a crucial time for Bayern, who is looking for his eighth title in the German League, as the top-ranked Bavarian club (49 points) is playing a fierce competition with Leipzig II (48 points) and Borussia Dortmund III (45 points).

The Polish international is the top scorer in the German League with 25 goals.
