Barcelona their finances are not in good shape until now but they were able to win the league last season and this season is playing very well too so I can say financial stability does not affect the overall game on the field when you can buy cheap players but the talent is outstanding, can you call it an anomaly?
Bayer Munich has good finances but they always buy players with their needs to fulfill their management strategy is very good, on the other hand from the player's side when offered to Bayer Munich where they have a quota to the European league which is definitely a subscription, popularity also cannot be underestimated, Munich is quite famous.
Elite European clubs are always having this advantage to keep themselves at the top despite having many troubles on and off the field, same happens with Barcelona which is currently facing worst finances still able to do their best and leading La Liga table.
Bayern Munich is always one of the strongest teams in Europe, and they are always capable of bringing players which they need for their best. Bayern Munich is one of the best clubs in world due to their rich heritage and amazing success even things are always under their control in Bundesliga, they are doing impressive job in Europe and always enjoying the best results.
