Lewandowski and Mbappe are no match of course. Lewandowski has been one of the best strikers in football history. Therefore it isn't too hard to understand why Bayern Munich aren't very willing to let him go now. Because he can still be very useful and even continue be the top scorer in the Bundesliga. But I'm afraid they are very likely to lose him this summer as it seems. Barcelona seem to be the closest team to sign him now as far as I can see. Chelsea are rumoured to make an effort for him too but Barcelona could still be one step ahead.
