Its not like they havent sold their stars in the past tho.If the player has clear intention to leave,he will be sold.
Distinctly remember Bayern having a deal(an oral agreement) with Wolfsburg for Dzeko(between the Hoeness bros) although it never quite came to fruition.So its not like they're 'Anti-Bayern' like Voeller is for example, either.
From what I've seen this guy has absolutely nothing special on him. Always seemed average. For some reason, has always been in Brazilian national teams, since U15. Gotta be an agent's thing. Next Piazon.
