I’m not sure why Alonso would join Bayern. Nothing at that club is deemed as success unless it’s winning the CL. I mean he’s beating them in the Bundesliga with Leverkusen so what is the point in going there.
I have a vested interest obviously as I’d love him to take over from Klopp when the latter leaves in the summer. Surely taking over at Liverpool is far more prestigious than Bayern. It’s a harder job too, more of a challenge to battle against Guardiola in the PL. Maybe Alonso hasn’t got the balls to take on the PL and wants to stay in a farmers league. If that’s the case then maybe I don’t want him at LFC.
Moving to the same league but just a different club is no greater challenge for Alonso, if he takes over Bayern Munich maybe he wants to take a comfort zone.
Maybe Xabi is thinking about how the Premier League job is very tough, just imagine Zidane refusing to coach the English team because he probably realizes how tight the game is here but he doesn't try any challenges which will obviously be more interesting if Alonso returns to the old club as a coach.
