It's very easy to misremember the past. I think we are guilty of looking back at every Potter game as an enormous success - they weren't. Aside from the last 8 games where we did really well it was largely patchy.
The bigger issue, as mentioned by others, is the quality of the next batch of loanees/youngsters coming through that will need to replace Tross, Caicedo and maybe Sanchez. It's a bit thin.
Fulham was a pretty poor performance.
