Jose Mourinho says the hurt Tottenham suffered in squandering a 3-0 lead against West Ham has changed the way they are playing.
Spurs briefly went top of the Premier League after they beat West Brom 1-0 at the Hawthorns on Sunday thanks to Harry Kane's late goal - his 150th in the Premier League.
The manner of the victory was a far cry from the start of the season where they were free-scoring and cutting teams open at will.
One of those were the Hammers as they led 3-0 after just 16 minutes, only for a late capitulation which saw them concede three goals in the final eight minutes to draw 3-3.
Mourinho's men have not been as expansive since, grinding out a 1-0 win over Burnley and an edgy 2-1 success against Brighton, which was followed by the late victory over the Baggies.
Asked about the impact of the West Ham game, Mourinho said: "I said that we were speaking a lot about it and working a lot about that situation.
"I am not going to say we are not going to lose matches or lose points in the last minutes, it can happen to anyone.
"We felt the pain against West Ham and since then strategically the team is behaving in a different way.
"The two clean sheets at Burnley and at West Brom showed the lesson - a team in the last five minutes that was very solid, it looked like the pain made a positive effort and the team improved after that."
