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.
Spurs managers Jose Mourinho and Anthonio Conte left with nothing, no success, and nothing to strive for. Tottenham Hotspur is a dormant club, with fans who are fed up with the club's inability to win a trophy despite appearing in top competitions and returning to the white hart lane with nothing. The owners are the ones undermining the good chance Spurs would have had, despite having top experience managers in the club, and yet they still mm resigned because the club has nothing to give other than a good competitive race for trophies and not accomplishing anything.
