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.
