Although 2012 transfers havent completed yet, Bayern has already signed Starke, Dante, Shaqiri, Weiser, Pizzaro, Mandzukic and promoted Can and Weihrauch. Hoeness and Nerlinger obviously have seen that Bayern has been lack of depth for some time especially at the end of last season with loads of medicore players like Usami, Pranjic, Petersen, etc that Heynckes never used throughout the season.
With already 6 new signings and 2 promotion, Bayern looks better in terms of quantity. However, I still doubt the quality of the signings. With all these signings, we still havent addressed our defensive weakness and lack of Plan B in attack. With all the new signings and promotions, I doubt Starke, Weiser, Can and Weihrauch will be given too many opportunities to play. Dante's match time will be limited even if he could be a better fit as Heynckes will still give Badstuber the starting berth even though he sometimes has a horrible showing against European giants and Dortmund. Shaqiri will be long term player for us as he will be backup for Robben or Mueller. Pizzaro and Mandzukic probably wont challenge Gomez's starting position as both players are relatively medicore at current age.
