A few contenders here (in my opinion) please feel free to add to this list
Roy Hodgson (Fulham FC) - getting them to a european final - beating the likes of Juventus on the way there.
Alex McCleish (Birmingham) - Best league finish (Top 10 in the premiership).
Harry Redknapp (Spurs) - Spurs in the running for a top 4 finish which is a good achievement for this season.
Ian Holloway (Blackpool) - I mean a top 6 in the championship - could you imagine if they went up? That would be a huge fairytale!
Paul Lambert (Colchester/Norwich) - Get a new job by beating that team 7-1 on the opening day of the season and take over and win league one with them - awesome
Rochdale - Finally leave the basement division after being there since 1974.
