There's a manager who took over a failing side that had been eliminated from the CL and Europa, then led them to the semi finals of the CL for the first time in 21 years. They beat Real Madrid 4-1, Juventus 2-1. He then completed the league double in his first season, and had consecutive league titles. He became the fastest manager in league history to reach 100 wins with that club, doing it in 128 matches. Since then, he moved to a bigger club and won 2 trophies with them, a club that hadn't won a trophy in almost 7 years. He followed that up by winning the league cup, a trophy they hadn't won in 8 years.
I want someone proven in the PL.
