lol what
What should the DFB do? You're not allowed to sign players from other German clubs? You are only allowed to spend 30m a season? Why would they even do that? The DFB should rather put a stop on the Hoffenheims and Leipzigs out there.
But they could do with another striker. What would be the difference to all the Falcao rumors for example? Would be even more expensive.
It's not good for one team to have so much power over the others. I recall reading statements from a Bayern chairman where he stated his concern over how one sided the league is becoming.
Saying this though, the main priorities of the German FA and Bayern are likely the same. They want total dominance in the CL, so I don't think they give a shit about thier domestic league any more.
