Well thanks for explanation. I did not know he's a Bayern fan. I feel sorry for him losing such a loyal figure who's also a leader, which is very very difficult to replace.He's a Bayern fan and knows him a lot better then we would... And what he says is likely true and makes sense anyway. He's obviously a lifelong Bayern fan, but always had the goal to play abroad one day and united is a logical choice.
My point is, there is no need to knock off how he was only saying all those things to please United fans. All footballers want their fans to love him and it is very natural he did what he did, plus the extra information that he's wearing a United shirt in an old photo (not a Chelsea or Pool shirt etc) which adds to his credibility.
