If later Xabi Alonso succeeds in giving Leverkusen the UEL title, that is an early sign and if in the next season Xabi is able to give Leverkusen achievements in the Champions League, I am sure Bayern Munich will try to get it and for now Bayern Munich will not do that.
Xabi has been with Leverkusen for almost 3 years, so he can get to this point in need of a process. So if Bayern want instant results it seems that is also difficult to happen. Because I believe Every coach must have a process, there are not many coaches who can give a champion when he just comes. So if Bayern want him, it is also the same as the previous coach because there is no definite guarantee from Xabi.
