it is true that Pochettino's task is very hard to be required to make changes to Chelsea's performance but on the one hand Chelsea needs a little more money because they have to replace several players who no longer have the enthusiasm to improve performance in the summer.
if Pochettino does all this wisely, I believe Pochettino's efforts will not be in vain to give Chelsea an upgrade to get the best place next summer.
What things shall be changed by pochettino from the club are
Mentality
Line up
Strategy
Management
The most important think to told the owner stop intervening the club with his own decision. Learned from some mistakes that happened in the potter's era when todd was deciding to buy some garbage players like mudryk.
Tod has zero knowledge about football and he was only being fooled by other team.
It's the best thing to keep him stay away from touching his own club with his horrible decision. This club is lack of quality right now.
The new owner was only destroying the club by fired so many professional staff when he has become a new owner.
