I am not surprised by this fact because basically the quality of the Chelsea team is no better than Newcastle, Aston Villa or West Ham. Chelsea are verry bad to be expected to be as impressive as their fans expect, meaning they are still in sleep mode for their last 6 matches even though he was able to win 5 points. LOL
The team is still devastated by the bad results it has suffered, but Pochettino still has hope of improving it if he is still trusted to serve as coach until the end of the season. Changes in strategy and player rotation are needed instead of relying on expensive squads to drop points in relatively easy matches.
In terms of squad quality Chelsea have the better players but with less experience playing in the premier league. The current problem with this Chelsea sode is that most of the players are very young and still lack that level of experience to compete amongst the top teams in the premier league at the moment. The team needs some experienced players to guide and lead this young ones, this is not entirely Pochettino fault.
