#4 Claudio Ranieri (Leicester City)
Claudio Ranieri announced his arrival in England when he joined Chelsea. The Italian brought the likes of Frank Lampard to the squad and led them to a Champions League semifinal. But he was replaced by Jose Mourinho in 2004. He then managed clubs like Valencia and Inter Milan, where he failed to win a single piece of silverware.
The Italian was the butt of many jokes and Mourinho himself called him "an old man who hasn't won anything." But Ranieri would enjoy the last laugh. He returned to England to manage Leicester City in 2015 and led the Foxes to a historic Premier League title against all odds, literally.
He also managed to beat Mourinho’s Chelsea on the way after which Mourinho was removed from his position.
However, in 2016, Ranieri was sacked after a disappointing domestic and European season.
