I'm interested to see how this situation is resolved. I could be wrong, but it seems to me that Ronaldo's ambitions outweigh financial considerations, so he can accept a pay cut (he still earns a lot from other sources) just to get into a top club playing in the Champions League (especially in Bayern, where he will be provided with an uninterrupted supply balls from Muller 
and from the others).
I think will for Cristiano Ronaldo cut off his salary for getting chance back participant on UEFA Champion League next season with Bayern Munich, maybe he will cut off salary about 20% until 30% for playing with Bayern Munich next season. Last ended his career actually Cristiano Ronaldo keep trying get performance on Champion League and try to get trophy before retired from football or moving to MLS League. Cristiano Ronaldo still have many passive income source and not only with salary as football player but also he have many kinds passive income, cut off salary and get participants on UEFA Champion League not problem for him. and from the others).
