Tel had already shown his erratic side in the first half when he found himself in a tight spot in his own penalty, then attempted to resolve the problem by delivering a perfect cross onto the head of an onrushing Leeds United forward, only for Kevin Danso’s desperate clearance to spare his embarrassment.
This was nothing compared to a bicycle kick in his own area that connected with Ethan Ampadu’s head, leaving the Leeds captain in a heap.
The Video Assistant Referee merely confirmed what everyone else in stadium knew, De Zerbi raising his eyes to the heavens as Dominic Calvert-Lewin slammed home the penalty.
After being a relatively low-key presence in his early Spurs games, which have included vital wins away at Wolverhampton Wanderers and Aston Villa, this was the night when the Italian’s combustible temperament bubbled throughout.
De Zerbi jumped up and down on the spot in disgust at slow play from his team in the first half, then incurred the wrath of referee Jarred Gillett, who delivered a touchline dressing down as the Italian repeatedly left his technical area.
He received a yellow card as things threatened to boil over late on, with 13 minutes of added time increasing the unbearable tension around the stadium.
No wonder De Zerbi looked so frustrated at the final whistle, because the door to survival that opened wider when West Ham United lost so contentiously to Arsenal on Sunday, suddenly closed again as they missed the chance to open up a significant four-point advantage going into the final two games of the season.
De Zerbi told Match of the Day that the pressure of their situation may have had an impact on his players.
“We didn’t play a great game – we played a good game,” De Zerbi said.
“I think we deserved to win anyway but maybe the pressure, the crucial game, the crucial part of the season, we suffered too much.
“Anyway I am happy because I watched my players with the right spirit, with the right mentality.
“We made too many mistakes. If we want to win we have to reduce the mistakes, but we knew before this game it will be tough until the end of the season, until the last game. It is tough for us and tough for everyone.”
On Tel, he said: “He is young and is a talent. I will kiss him and hug him. He doesn’t need too many words. He was sorry for the mistake. It can happen to a young player.”
De Zerbi added: “I think we have to consider the result, but we also have to consider the performance. We played a good game, we are making points – in the last four games we made eight points.
“Congratulations to Leeds. They played a great game. They have to play the last game at West Ham and we’ve no doubt that they will play the same way.”
