Been critical of Vincent Kompany even before the season starts is not a bad move. It doesn't mean that we are going to see him suck, who knows maybe Bayern will win the league very easily, like with 10+ point difference. That doesn't mean that you can't just assume that Bayern could have gotten someone with more experience back in the day, this is Bayern we are talking about. Hiring a manager out of a relegation team at England is not what Bayern should be doing, even if he turns out to be good, this isn't the place to check that out.
Hiring a manager from a small team that got relegated on the English Premier League last season is not too good for Bayern Munich, but some people were thinking that it is a good signing which I wanted to agree at the first place, but when I checked the margin, I also thought that it was a wrong move for Bayern.
On personal experience, he has not yet experienced coaching any big team, starting his big team career at Bayern is not that good, but he can as well do well since the team is already built and have quality and world class players that can win them titles.
Bayern is expecting fans to just stay and watch, maybe he will turn out to be great, maybe he will turn out to be terrible, that is not what Bayern suppose to do. Let that be done by some other team, a lower level team, hire Xabi for whatever price you need to, pay 20 million a year to him if you have to, and get him, because he proved himself, or get someone that level. That's how a team like Bayern should be acting, getting a manager they know is good and already proven to the world. If they hire someone who hasn't proven anything at all, then I am sorry but then everyone will question the decision even before the season starts, that's just the way it is.
Alonso also started unexpectedly but ended well, he has already proven his worth as a great manger even though it wasn’t in a big team like Bayern, I will be expecting similar performance from Vincent Kompany.
Hiring Alonso would have been better, but he said he cannot leave for now that he will stay additional season at Leverkusen if not Madrid and Liverpool were also in the race to sign him; but at the end of next season, he will decide if he is leaving or not and which team he will decide to go.
