Even if Lewandowski stayed at Bayern, it would not change the problem that the club would be forced to deal with the problem of his departure. Well, if he left a year or two later (due to age) - I don’t see any fundamental differences. Top clubs solve the problem of leaving their stars in advance, for example, Real got rid of Ronaldo long before he passed his peak (or at least an acceptable level of play to be in Real) and nothing tragic happened to Real.
But of course it's funny that everything is shaping up so that in the end Ronaldo can be the savior of Bayern in the winter.
Don't say even if lawendowski had stayed at Bayern Munich they will still be struggling,this is a player that have been playing for Bayern Munich for up to five years now and each of those years he has scored more than twenty five goals, he is world class, and the best number in Europe for the past eight years, such players must surely be missed if they leave any club, funny you said everything is shaping up for Christiano Ronaldo to fill his boot, but those are the kind of players you replace the Poland ice with.
I didn't understand your point of view. In your opinion, when did Bayern have to change Lewandowski? In a year, in two? Or then when it would already become obvious (for example, due to the failure of the season) that he is no longer as good as before? Serious clubs do not wait for problems, they solve them in advance.
As for Ronaldo, as funny as it may be, he will be the only option for top clubs that want to get themselves a qualified centre-forward this winter.
