Every manager that have the experience to be at the white hart line unde levy knew that the club won't achieve anything with such policy from the board, mourinho and antonio conte speak up about that multiple times and yeah pochettino is the one with the greatest achievement under super limited resources. It's a whole new level for poch to bring chelsea with his idea to bring a success that nobody can imagined.
As for Pochettino's future success at Chelsea or, conversely, failure, a lot depends on what role the club owner Todd Boehly will play. For in my humble opinion, a big role in Chelsea's relatively unsuccessful results lately is that Boehly fancies himself a genius of scouting and the transfer department of the club, although the sobering reality seems to say something completely different.
That's right, the club owner should focus on administrative matters and don't evolve himself in the choices of the coach, many clubs owners want to play the role of the coach and this will surely lead to very bad results, i really don't want to see Chelsea experiencing the same situation as previous season
