Allardyce got us promoted and kept us up on a shoe string budget, I don't believe the argument that he was playing with Rioch/Todd's money, the money we spent was as a result of getting promoted to the richest league in the world.
You fail to acknowledge the players he brought through and cost us nothing, Nolan, O'Brien and Hunt and completely ignore the players he brought in for very little money and were highly successful for us like Ben Haim, Michael Ricketts, Kevin Davies, Speed and Abdoulaye Faye.
Even players he brought in but weren't given their opportunity by subsequent staff have proved good players like Dzemaili and Al Habsi.
Allardyce left because it was obvious he'd taken us as far as out budget would allow, I never held it against him leaving for Newcastle, he was very ambitious and quite rightly so having turned us from a mid table championship side into a top 6 Premier league side. You can't argue with his success or how he did it, we won't see such a level of success for a long time.
