that was ironic that Leicester performance inversely proportional with the last season because the champion currently they must fight to avoid relegated zone but in my point of view that sack Renieri won't solved the problem and sacked the coach in the middle of season is very risky
This has become a trend, the managers leaving/retiring or being sacked in the next year after they win the League. Last winners of the Premier League: Mancini gone, Ferguson gone, Pellegrini gone, Mourinho gone, Ranieri gone. Other than Ferguson's departure, the rest have come, I think because of the players attitude and playing. They players have been slacking in the season after the PL win and have had a slow start in the league next year. This was the case at least for the last 2 sackings. Mourinho and Ranieri as the players didnt want to play the same intensity and dropped loads of points in the League.
