I'm wondering how Pochettino wants to rebuild Chelsea for the next season because the Chelsea we saw this season had lots of mistakes and they are not in a good situation at all also many expensive players they bought this season are not helping the team and they are not performing well as they should perform.
Regardless of that Chelsea needs to have a better atmosphere and the situation they have is not good for a team like Chelsea at all.
I think Chelsea should wait for Pochettino to give them a list of players he needs for the next season and then they should hire just the players Pochettino needs any other player Pochettino doesn't need should not be hired doesn't matter how expensive and famous they are.
No one is sure how the season will be for Chelsea because Chelsea have used several coaches before now, but but we still need to give pochettino a try desperate the challenge of the club especially this season. Maybe pochettino strategies may work in the coming season for the club.
