Spurs have made the same mistake they did with Mourinho. They are a club determined to go backwards I'm sure of it!
When Pocchetino was the manager, their style was fast attacking play. It was great to watch and whilst they blew the league, they got to a CL final and he deserved a lot of credit for that. They were picking up players who could play the way the manager wanted them to play. The club was being well run.
When they refused to back him, they brought in a manager who plays a solid formation which is mainly focussed on not conceding. It was the opposite football to Pocchetino and, no surprise, the players didn't take to it.
They've now picked a manager who took Wolves and made them a solid team who countered. It did well enough for them but was found out. They had some good players, but his system was simple and effective.
Nuno's style doesn't match up with Pocchetino or Mourinho's. As a result, they are likely to end up with unhappy players trying to play a system which doesn't suit them. Let's be honest, if you've had a taste of playing fast, attacking football then anything else is boring. Imagine how Rodri must've felt moving from Athetico to City!
