For me
Carlo ancelloti(chelsea) 1st season and he do well with chelsea
Roy hodgson (fulham) now fulham at the final europa legue
Harry redknapp (spurs) bring the spurs at the top 4
roberto martinez (wigan) underdog, top 4 destroyer
Also if can included
David moyes (everton) 1 half at the season everton look struggle, but now they are safe.
