I'm not in agree with you. I don't think that Ronaldo will cut his salary and I don't think at the same time that Bayern will take him. Maybe a team like Roma can do that for only a question of income from shirts ecc. but
I don't think that a team like bayern really necessitate a player like him. Then, ronaldo is so difficult as player and needs a team built around him, and I don't think that Bayern will do this.
You say some unhealthy stereotypes about Ronaldo. Even compared to Lewandowski, he is more of a team player (and, as you can see now, a lot more moral) if you remember, Ronaldo has the most assists in the Champions League in history. In my opinion, he will easily replace Lewandowski without any restructuring of the team game.
