There are rumors about Ronaldo getting into Bayern Munich but Bayern has landed Sadio Mané, Matthijs de Ligt, and Mathys Tel, so getting Ronaldo is not possible, and there are said that management from Bayern Munich doesn't like how Cristiano Ronaldo is playing, because he doesn't do any team play and wants the spotlight for himself, he is like the Kobe Bryant of the football world but surely he is one of the best footballers in the world, but nobody wants to sign him, and pretty much he is old enough for a transfer,
For this rumor to become true, a lot of "ifs" need to converge. If Ronaldo still becomes unnecessary for Manchester United, then they will want to sell him, if the price of Ronaldo drops significantly due to a bad game, then perhaps Bayern will consider this transfer, but I doubt it, because his age for football is on the verge. Moreover, Bayern already once answered these rumors that they were not interested in Ranaldo.
