As such, the Polish striker will miss both legs of Bayern’s quarter-final tie against Paris Saint-Germain in the Champions League.

“Robert Lewandowski has strained a ligament in his right knee,” a statement read on Bayern’s website.

“The FC Bayern striker will be out for around four weeks. After Poland’s 3-0 win over Andorra, Lewandowski returned early to Munich, where a diagnosis was made by the German record champions’ medical team.

“The 32-year-old had scored the first two goals in Sunday’s match before having to leave the field after an hour following a clash.”

Lewandowski has scored 35 goals in 25 Bundesliga games for Bayern so far this season, while he has also netted five goals in six games in the Champions League.

In addition to missing Bayern’s tie against PSG, the current frontrunner for the European Golden Boot will also be unavailable for his side’s Bundesliga matches against RB Leipzig, Union Berlin, Wolfsburg and Bayer Leverkusen
