Hes been a mixed bag really, tough situation he walked into, made some good signings, dropped some changers, sold some i would have thought clever to keep, signed some good young players, struggled to sell players. id give him credit for bringing down the average age of the squad.
Another three years, if you decide to go a certain way structure and philosophy wise, you have to back it, so ill give him the three years, but it needs to be better then the last, with the squad in not such a desperate state as any mitigation.
