I don't really understand why you always associate Bayern with Ronaldo even though we also know that the officials there don't really agree with Ronaldo and this is indeed a problem that is difficult to solve.
At the moment Bayern's focus is still on Kane but it may change at any time but this will happen when Kane is already difficult to bring and Ronaldo may be an option although I'm not too sure about that.
At this time, Bayern should concentrate on Harry Kane; Ronaldo should depart, but not to Bayern Munich. Due of the necessity to add long-term players who will develop with the present team. Harry Kane is a young man by comparison.
Bayern's primary target is Harry Kane, and I'll be happy if they can sign him.
Ronaldo can indeed be an option but Bayern are quite aware at his current age he will not last long and from the perspective of Hary Kane's age he is much better of course he is the main priority.
But of course they also have to look for other alternatives because indeed with Tottenham's current condition it is clear that Kane is still difficult to join in my opinion because it seems he is finding his form again under Conte's care.
