Mauricio Pochettino does not know whether he will be given the time to rebuild Tottenham after another disappointing Premier League result.

Spurs' horrible start to the season continued as they were again sub-standard in stuttering to a 1-1 draw against Sheffield United, leaving them with just three wins from their opening 12 league games.

Pochettino has spoken at length about how the club were entering a "painful rebuild" after their run to the Champions League final last term, but no one envisaged just how painful things would be on the pitch as well as off it.

They led at the Tottenham Hotspur Stadium through Son Heung-min, but George Baldock's 78th-minute leveller earned the Blades, who also had a goal marginally ruled out by VAR, a deserved point.

Pochettino said as recently as Tuesday that he would like to see out the remaining three years of his contract, but now has hinted he might not be given that much time as the pressure increases.

"I think you can see that yes, we need to find the balance," he said.

"We are building a team during the season, while competing in the Champions League and Premier League, the toughest league in the world, and always that is dangerous, this type of situation can happen.

"You expect better results than you get. Of course we are in a process to build and we'll see if we have time to build what we want."

On his side's limp display, he added: "We are disappointed because we knew we were going to find a team who would be aggressive and very energetic, well organised.

"This is the worst opponent you can have when you come to play from Wednesday in the Champions League, a very long way.

"I am disappointed because in the moment we broke them down to go and lead 1-0 in the second half, not keeping that advantage or scoring the second goal in that moment when we dominated the game.

"We feel so disappointed, I don't know the word to use. Upset or frustrated, but it is not a happy feeling."
