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.
Tottenham Hotspurs had many years with strategy to grow up players then sell them to enrich the club budget. They have changed recent seasons but success has yet come to them. No title has come to Tottenham and they only have two final matches, one with Pochettino and one with Mourinho but they sacked Mourinho a few days before that final match.
Tottenham wasted best times in career of Harry Kane and Son Heung Min and maybe those players will sooner lose their best performances when they are getting older or will leave Tottenham to find new opportunities.
