Robert Lewandowski will require an operation on his groin, Bayern’s interim coach Hansi Flick told reporters Tuesday.
Flick, who has taken charge of the team following the sacking of Niko Kovac, says Bayern’s star strike is still able to play but that surgery is likely.
“He (Lewandowski) has problems, but no pain and it’s clear that something has to be done.
“He will think about when he wants to have it. It would not be good to interrupt the run he is having but it will be his decision and we have to respect that.”
Lewandowski is in the form of his life.
The Bayern Munich star has scored 20 goals in 16 matches, including 14 in the first 10 Bundesliga games of the season – a new record.
The 31-year-old, who has five goals in this season’s Champions League so far, is set to play against Olympiacos on Wednesday.
The Poland international is the highest scoring foreign player in Bundesliga history with 216 goals in 300 games for Bayern and Borussia Dortmund.
