Concerns began to emerge over Pochettino performance after only being able to win one win in four games. Initially it was hoped that he could improve Chelsea performance, but he failed to meet the expectations of Chelsea management and it was still difficult to win even though several quality players had been brought in. Chelsea played very badly, like a small team that had just been promoted to the EPL, their game had no direction, they still had difficulty building connections between their players.
I think Pochettino future with Chelsea will not last long if Chelsea performance is still bad. When a team has made major changes but is still having difficulty winning, then the coach's performance needs to be questioned, whether he is able to formulate a good strategy or not.
Theoretically, Chelsea should be patient when other clubs are actively involved in European competition and then they will have an advantage over them. The problem is that Poccetino can be sacked before this period because if you lose to Nottingham, then all other options do not matter. Therefore, in the next away game with Bournemouth, Chelsea only need a victory, and then a home victory over Aston Villa. By the way, Chelsea have a rather easy calendar (up to the 9th round when they play with Arsenal), so there are chances to return to business.
