The big mistake Spurs and Pochettino made after Lucas Moura's dramatic winner

Mauricio Pochettino has revealed the mistake he and his Tottenham Hotspur players made in the Champions League semi-final win over Ajax.

Pochettino admits he lost his composure after the Brazilian scored the winning goal on the night.

"It was a massive achievement for us," he told talkSPORT . "It was one of our dreams when we started the process here at Tottenham. "We've worked so hard and we have shared a lot of tough moments, so when you achieve something that nobody believed was possible, it is very emotional.

"And of course, we know how hard we work to reach this level, which is why it is difficult to keep your emotions inside.

"When Lucas Moura scored that third goal, in this moment I lost my head, I lost my composure and I nearly regretted it. When the referee said, 'one minute more', I wanted to kill myself!

"We were celebrating before we finished the game and in that moment we realised what a big mistake we were making because we jumped and ran inside the pitch and we believed the game was finished, but then we needed to defend again for one minute.

"It was the longest minute of my life.

"The best memory is when we finished, it was amazing – a big hug with my people, my son, the players, the staff. It's an amazing memory."
