Mind you that Mauricio Pochettino has coached only one English team, and that's Spurs, he also didn't win anything at Spurs, but winning nothing is typical of Spurs anyway, notwithstanding who's their manager. Pochettino knows the league quite well, he was manager of Spurs for over five years, thus he has the experience of the league, but not of winning any title in England. Well he is now manager of a bigger club (Chelsea), with a bigger history, so we'd see how successful he can be (though it definitely wouldn't happen immediately).
