He arrived after Mancini and after the original Etihad/Etisalat deals were signed. So he had absolutely no part in those. Also he wouldnt have needed to go out and find a company to buy the image rights, as the father & son behind Fordham already had relationships in Abu Dhabi. He simply wasn't a prime mover behind any of that.
Neither is his name mentioned in any of the Der Spiegel emails and nor was he a witness at CAS.
There's a lot of hot air about whether he was, or wasn't, involved in any of the stuff related to the charges, and what his new role means for the outcome of those. The simple fact is that he was offered a challenging new role and decided to step outside his comfort zone and take it. He had little or nothing to do with the events leading to the charges in my view and nor do they, or any supposed outcome, play any role in him leaving City and joining united.
