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.
No, pochettino already had interest in hiring some players but the main problem is if the player was rejecting chelsea's offer.
Pochettino was trying to hire manuel ugarte, but it's failed caused by the player was choosing PSG as his next club. The plan doesn't go well in this case. It's the main problem that is facing by pochettino right now caused by chelsea looked like unattractive due to the its poor performance in the previous 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.
At least going back to the top 4 and qualified for UCL is good enough. I don't even put big expectation for him and you do know what i meant.
Pochettino never won EPL. That's why i will not put a very big expectation for him.
