Bayern Muenchen toward Evolution

Louis Van Gaal is a new manager for Muenchen. He is famous for his discipline. Since he take care Muenchen,the club has begin it's evolution. Just imagine player like Lucio whom just became part of Brazil team which gain Fifa Confederation title - will be replace by Edson Braafheid - a much younger defender. Lucio is so down with this condition. If a senior player could be get rid by management,how about other players like Andreas Ottl, Christian Lell or even Luca Toni? Muenchen surely will respect player contracts but if they want to leave club will let them go. Even Muenchen hot commodity Frank Ribery will be sold if any club could paid 50 millions Euro. Is selling all valuable player a good way for evolution? I think Van Gaal will not last for one season.
