Maybe its possible for him that he will be fit and can play for Bayern Munich in this game against Paris , but its a high risk for him if he gets injured again in this match.
If that will be happen so i guess then it was it for him for playing in the german league and to break the record of the scored goals.
For sure is a half playing Lewandowski better that no one but if that is right i dont know , but we will see it.
