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.
Bayern Munich only team have active on window transfer with most expensive values than other club like Dortmund, Leipzig or Bayern Leverkusen, first transfer made by Bayern Munich success get Sadio Mane from Liverpool and have transfer values about 40 million euros,. Still have other transfer made by Bayern Munich for next time if success sell Robert Lewandowski to Barcelona, other Bundesliga team still waiting what transfer made, actually with Dortmund they have sold Erling Haaland to Manchester City and get much money but still not active to get new player on window transfer.
