Well when it's comes to winning of titles I think pochettino isn't actually the right man for the job because it's believe that he has some kind of bad luck for attracting trophy for his club and we all saw that during his coaching career at Tottenham although he managed to play the champions League final and as fate has always deem it he lost that final too to their premier League rival.
In their last match, Chelsea had difficulty getting a win, even though the team that Chelsea has is actually quite good and it should be easy to score goals. In reality, perhaps the strategy used by Mauricio Pochettino is still not successful in bringing Chelsea back to the top five at the top of the standings, and Chelsea should probably consider changing to a better trainer.
