So far I didn't see any special news about Chelsea after Pochettino joined the team and it seems like Pochettino didn't show interest in hiring players yet, not at least they tried to keep the list private but the Chelsea I can see need a revolution and Pochettino should release many players they don't need to have the empty spot and hire the players he needs to have for the next season.
I expect to see Pochettino help Chelsea to be at the top of the premier league again in the next season 9f everything goes well.
When Graham Potter came to Chelsea in replacement of Tuchel, everyone saw how he came and was just doing things as if he will do something meaningful for the club and last last, it was nonsense effort he added to the team, he was one of the worst Coach ever signed by Chelsea and after that, Lampard came and pictures were everywhere in the media even when they are in training session, he was just over confident and showing off until they became nothing, there was nothing achieve by these men. Pochettino should better stay underground and do his strategy that will help the team than running up and down without any achievement.
