It depends on how much the buying club are willing to subsidize I guess.
My problem with Ozil is that characters like him are what starts the rot in attitude, and in a squad like ours that is devoid of big players, his influence is huge and can be extremely toxic as Emery found out eventually. If, or shall I say, when Ozil stops busting his tail, how can you as a manager justify asking others to keep busting theirs?
