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.
yes I also doubt Pochettino who is currently with Chelsea, my doubts lie in their transfer market this time by looking at the comparison of the players they released and they bought this time. Worse, they left almost all of their main squad last season and only a few names remained. Mason Mount, Loftus Cheek, Cristian Pulisic, Kai Havertz, Mate Kovacic, Edouard Mendy, Kante and their captain Cesar Azpilicueta have all been released and there are still a few players left. Then look at the players they have brought in, like Christopher Nkunku and Nicolas Jackson, of course they are not comparable to the players they have released, both in quality and mentality. I think with transfer management steps like this Chelsea will likely become a mid-table filler club in the EPL standings next season.
Pochettino cannot do much with such a squad composition next season, on the other hand he is also not the typical coach like Ancelotti and Mourinho who are highly respected by their players. My prediction is that they will no longer be the favorites to challenge for the EPL championship next season, such as Man City, Arsenal and Man Utnited.
