You put aside the fact that Bayern don't want Ronaldo at Bayern.
And with this it will actually become clear that they can't bring in Kane as you say there are still many options and it's not just Ronaldo. Bayern still adhere to their philosophy and Ronaldo is not included in theirs.
Bayern still have to find a striker but definitely not Ronaldo.
Yep, Bayern decided not to sign Ronaldo, Bayern pursued other transfer targets. Case close
And it looks like Julian Nagelsmann is not worried about Sadio Mane's slump in form,
he still believes Mane and instead labeled him one of the best players in the world.
Since World Cup is to take place in November, all eyes will be there to find new talents.
But there will be very few quality player options that can significantly improve a team's performance.
