Tottenham assistant manager Cristian Stellini refused to criticise his players after defeat at Wolves.
Adama Traore struck the winner for the hosts.
Stellini said, "I think the performance was good, particularly in the first half when we controlled the game in every aspect. We had some chances to score. We were not so nasty in the way to score. When you have a chance like this, you have to kill the game. The game was under control but then in second half we struggled a bit at the start but after 10 minutes we adapted to the situation and we controlled the game.
"We had another chance with Sonny that hit the bar. After that I think they had some intensity in the game, winning some offensive duels and that create a situation where we struggle a bit and the game changed, but they found a way to score and we didn't. This is the history of the game.
"We were playing well, and the pace and we controlled the game. There wasn't reason to change. After we change because there was a reason to change because we needed more energy and to interrupt their pace in the game, but only one detail changed the story of the game."
Asked about his players' attitude, Stellini added: "Today we showed a great mentality because we came here in a situation against a team that is similar to Leicester, a great team with a good squad and we control the game for 60 minutes.
"We play different if you compare the game in Leicester to the game today. I think the mentality today was good. It is a lesson we have to learn because when you start the game and you control the game, you have to kill the game. This is a lesson we have to learn today."
