Well, I don't think Bayern hate us because of these transfers. Sali and Kovac are/were not hard to replace and Bayern didn't go to the max to keep them. So I think they don't care that much that these players left. Both are squad players, not star players. If we would buy Lahm or Sagnol, now then they would be angry.
Pizarro is good. In January German media reported that he demanded 4 million p.a. from Bayern. If we get him for 2,5 million, fine. But I have to say again, he cannot replace Trez. I would like to have Huntelaar, too. He is a real boxstriker with scoring-instinct. Than we could rotate Pizarro, Del Piero and Huntelaar. That's good. Plus Palladino (and maybe Bojinov).
