Money isnt the problem for Bayern Munich it never was. They are only trying to be smart and get a striker that can stay longer then a year or two. When Lewandowski came to Bayern Munich he was young,i dont know if you noticed but Bayern Munich dosent buy old players at all.
Of course, Bayern have better finances compared to other teams. I agree with your opinion that Bayern prefer young players over old ones. rumors circulating about ronaldo going to bayern munich it is a baseless rumor and has been denied by the director of bayern that the news is not true. now bayern have mane and i don't think bayern will choose the option to improve the front line again this summer because sadio mane is the right signing for the bayern munich attacking side to start next season. Lewandowski problem has not found a bright spot for now although several clubs are interested in getting his services but Bayern still want him to stay until his contract expires.
