Chelsea is a team that has been discussed a lot since Pochettino was appointed as coach. But are you sure Pochettino is the right coach to bring Chelsea back into the top 4? I'm still not very sure about his abilities, but he is an experienced coach in the Premier League with Tottenham in previous seasons.
In the case of Pochettino to make Chelsea perform better next season is not something to really worry about, we all know he has some previous experience in the Premier League but that cannot certify him to be the perfect man for the job yet. The premier league he left some years back is not as the same as the current ones. The underdog teams have now improved in the league and have become worthy opponents to also look out on. We have to wait until the league starts and see the professionalism Pochettino is going into the team to make them better by next season.
