There is no reason to panic at the moment, but the summer will be a real challenge for Hoeness.
VDV is the most likely target IMO. Doesn't look like the HSV has sorted out his problems in the winter break, so VDV might want to leave the sinking ship at the end of the season.
I've heard, Hoeness hasn't yet talked with Ribery because he didn't wanted to put too much pressure on Deisler. Now after Basti's retirement, I hope Hoeness takes the initiative to get Ribery.
Re Boateng should stay in Berlin for two or three more years. He's not yet prepared to play at Bayern and would probably end as a second Rau.
Does Gerland have some young German midfielders in his team? Only know Kopplin and Kroos. Kooplin is a defender, right? And Kroos is a bit too young I guess, but maybe there is an USEFUL player in the Bayern youth or Bayern II team for the bench?! Btw what has happened with Görlitz? Is he injured?
Regarding Hargreaves, before the retirement of Deisler and Brazzo's decision, I was 100% sure Bayern would sell him at the end of the season, but now with at least 5 mids (Scholl, Karimi, Brazzo, Deisler, Dos Santos) leaving/retiring, I seriously doubt it. Ottl is not really an option yet and going into a new season with probably 5 or 6 new midfielders, who will need time to settle in, is not really Bayern-esque, is it.
All in all, Hoeness will have some sleepless nights, but I hope he takes the money they have and invest it into some international players in the summer (e.g. Ribery, Robben or Riquelme), and the remaining gaps were filled with some players from other Bundesliga clubs (e.g. Schlaudraff, Altintop, Bastürk or VDV).
And who knows, maybe it's a start of a bright future...
