I'm not going to talk about their performance before the start of this season because we know Chelsea the last season had many famous and expensive players also they were in a situation where I thought they are on top of the table because of the bad performance of their coach the team lost motivation for the rest of the season and that's why Chelsea didn't get anything.
But none knows about the future of Chelsea in the next season with Pochettino.
Last season was a failure for Chelsea in every way. They spend a lot of money but fail in achieving it. And this season they are trying to fix it, they hope that Pochettino can really manage and get Chelsea back to their prime and rise from the slump last season. They have taken several steps, starting from changing coaches and buying several new players who are considered quite talented. And still hunting for several players to strengthen the squad on all fronts. However, will they experience the same problems later when the club is playing? This will be Pochettino's tough task later.
Stabilizing Chelsea's squad is a difficult task for Pochettino. We still don't know if he will succeed. Chelsea's last season was very bad. This team was failing to win even against weaker teams. The mutual understanding between the players was not good. Pochettino's main task next season will be to improve the understanding between the players. If he can do that, Chelsea are likely to get a better performance. But I don't think Pochettino should be trusted too much. He did not succeed with the PSG team despite having a very strong squad.
