I think he has made a very easy choice. He is going to a side who went to the final of the champs league, probably the best team in the competition last year? (Apologies Robert, Natalia, whatever) They are destroying their league this season and have genuinely world class players, perhaps as many as 8 plus a stackfull on the next tier down. The current manager must be puzzled.
He has gone for guaranteed success, and I dont blame him, that's what players do too. I expect he will stay there 2 years then we will see him at Fegie's funeral before being unveiled there.
