He hasn't improved the club since coming, at best he's helped the club tread water while throwing money away by the handful. The best signing he's made for the club was Fernandinho, everything else has been truly awful business. Either absurd cost, poor players, or just poor timing like the waste of money that Bony was in January. That's not an indictment of him as a player because I rate him, it was just poor business.
If you honestly evaluate his performance in the transfer market and not come to the conclusion that he is a complete fraud I don't know what to say
