Ranieri hasn't really rotated his pack, however they have played 10-15 games less than most of the other teams around them. They went out of the FA Cup in the third round, and the League Cup in the 4th (after playing kids/reserves all the way through). Also, the 3 most substituted off players in the whole of the Premier League this season are Albrighton, Mahrez and Okazaki, so he is quite good at 'resting' his players during games (if that makes sense!?) Maybe it is just that other teams are struggling fitness and energy wise due to Europe/long cup runs etc.. making Leicester look quicker? In my opinion this has made them an easy target for the doping/PED rumours, and hopefully I'm not proved wrong......
