Spurs have won just two of their opening eight games in all competitions this campaign and hit new depths on Tuesday when they were dumped out of the Carabao Cup by League Two Colchester.

They are sitting 10 points behind Premier League leaders Liverpool, and some fans on social media were calling for Pochettino's head, with #PochOut trending on Twitter.

Although the Argentine claims this period - which has been underpinned by dressing-room unrest due to the future of so many players being in doubt - is not the toughest he has endured at the club, the lack of wins is stinging.

"Of course I am suffering. This is my sixth season here and I am in an unbelievable environment here," he said.

"The training ground is amazing and we have the best stadium in the world. But football is about glory, it is about winning.

"The challenge is to get back there and I told you we are going to fight to try to make this possible to try to change the history of this club."

It is not only results this season that have contributed to Pochettino's grizzly mood as he revealed the Champions League final defeat to Liverpool was one of his lowest moments in the game.

"In football I suffered two big disappointments," he said.

"One when I was a player and there was the penalty at the World Cup.

"It was always my dream to play in a World Cup, my massive, big dream.

"Another day was with Tottenham to win a trophy and the closest to win a trophy was of course the Champions League and it was made even bigger because it was the Champions League.

"It was more than a dream. In that moment I felt disappointed and then I took a train to Barcelona and again you are like depressed.

"But I am happy now because I am positive and of course this season is going to be another massive challenge to change the game and have that energy to try to be contenders and try again to fight for big things.

"I'm going to try until the end."
