I love how people are writing off Leicester for next season, for the same reasons they wrote them off as late as December this season. Leicester's most valuable asset is Claudio Renieri, and if they hold on to him he'll keep them challenging for top 4. We shall see how things materialize.
It's fair enough to believe they will drop down the league next season when you consider how literally everything has fallen for them this season, a virtual lack of injuries to their most important players who have missed just a handful of matches between them ; Kante, Vardy, Mahrez, Drinkwater, Schmeichel, Albrighton and Huth. Add to that their lack of other games so far this season ; Leicester 36, United 48, Liverpool 49 etc. etc., they could even recently afford to give their players a whole week off mid-season to refresh themselves before another week of light training, that's 2 full weeks off between matches.
Compare that to teams such as United and Liverpool who played 4 games in 11 days whilst Leicester were enjoying themselves on the beach or golf course. They are going to be bright and full of energy for every match.
Next season I don't doubt Ranieri will still be there, Vardy too as he's 29 yrs old and in the middle of his 'Career Season', the same can be said for Albrighton, Huth, Morgan and maybe Schmeichel too. But I expect a queue of suitors for Kante, Mahrez and Drinkwater.
Next season you can add at least 6 CL games to their schedule and maybe they'll drop into the EL and get to play another 6-8 games or more. Add that to their small squad and loss of at least a couple of their stars, the strengthening with new managers of the 'Moneyed' clubs and the PL cash for everyone to bring in fresh blood ... and next season all of sudden begins to look daunting.
