Tottenham chairman Daniel Levy admits he hired Jose Mourinho and Antonio Conte seeking instant trophy success.
Levy explained their appointments at a fans forum this week.
"I want to win as much as everybody else, but the frustration of not winning and the pressure from maybe some players and from a large element of the fanbase, that we need to win, we need to spend money, we need to have a big manager, we need to have a big name, it affected me," he said.
"I had gone through a period where we'd almost won. With Mauricio we went through some very good times. We didn't quite get there but we came very close and we had a change in strategy.
"The strategy was let's bring in a trophy manager. We did it twice and look you have to learn from your mistakes. They're great managers but maybe not for this club.
"We want to play in a certain way and if that means it has to take a little bit longer to win maybe it's the right thing for us. That's why bringing Ange [Postecoglou] in was from my point of view the right decision."
