Hammond was a good player (arguably better) when we signed him, Bart has always been good - just never been given a chance and the reviews of Perry have been very mixed.
When AP joined he said he asks/demands players to play to 95% of potential every week - he doesnt however seem to have done this (with one or two exceptions). Thats why we are so far under-perforing.
To many good players, playing like average ones.
With the team we have, you'd need 6 or 7 playing to full potential and we would be too good for nearly every team in L1.
