#2 Antonio Conte
Antonio Conte justified his reputation by winning the Premier League with Chelsea in his very first season. He had won five titles with Italian giants Juventus before coming to Stamford Bridge.
Though it is often been said that managers take time to adjust in the Premier League because of its merciless competitiveness, Conte found his feet from the very beginning.
However, his relationship with Chelsea board and players eventually started getting a bit tarnished with time and consequently, the team's performance was awful. Conte made way for Maurizio Sarri in Chelsea earlier this year after giving the London sides two titles.
Since he is well aware of the nits and grits of the Premier League, Conte can be a good replacement for Mourinho.
