Potter is indeed very good to train a club which in fact is an ordinary player without star players but indeed for a club like Chelsea, Potter's qualifications are clearly not capable and indeed this is also the case even though his decision is at Chelsea but of course there are those who play a more role and that is management there that made him at Chelsea and made Chelsea not play as well as before.
Now blaming each other is also useless for Chelsea because what they have to do now is improve their performance so that a dark season like this one doesn't happen again for them.
Poccettino has let several players leave, it seems like he will create a new formation with new players who will be bought lately and strengthen performance to be able to return as strong as before, hope is with Poccettino
The understanding between Chelsea players is not good. And so I would say Pochettino should rebuild the Chelsea team completely. Chelsea have a lot of talented players in their squad. And so coach Pochettino has to sell several players and find new talented players. I believe that if Pochettino is given enough time, freedom, opportunities, and funds, he will be able to stabilize the Chelsea team. Next season we will see consistent performances from Chelsea.
