Chelsea have since struggled to adapt with the huge changes to personnel and pochettino has not been able to galvanize the squad that was already on a freefall having work under Thomas tuchel, Graham potter and frank Lampard last season and also with the sweeping changes on the front of transfer I think Chelsea are still coming to terms with pochettinos method which notoriously demanding and require high fitness
I think Pochettino should be given another chance after this year because he is currently in the process of getting to know the team. This will last for 1 year and as their adaptation to the team increases, they can achieve greater success with the team. What is needed for Chelsea is time and they must get that time by holding on for another year.
