Mauricio Pochettino's warning for Tottenham despite win over Manchester United

The Tottenham manager is desperate to keep his side grounded following Monday’s 3-0 win at Manchester United

Mauricio Pochettino has warned his Tottenham side will "crash" if they start to believe their own hype.

The Tottenham manager is desperate to keep his side grounded following Monday’s 3-0 win at Manchester United.

The rout has only has increased the expectation among fans as the north Londoners look to mount a push for the Premier League title.

And Pochettino won’t let standards slip after sending out a warning that Spurs have nothing yet ahead of Sunday’s trip to Watford.

“It’s easy to talk about perception,” said Pochettino, who will be without in-form keeper Hugo Lloris due to a thigh strain. “When you’ve beaten Manchester United 3-0 in Old Trafford, an historic victory, it’s easy to say our performance was fantastic and they were not so good.

“But when you watch again the game I think the line was very thin, to be in the left or right, in the positive or negative. Still in the last three games we’ve conceded a lot of chances. Our keeper (Lloris) made an unbelievable save to keep the team alive.

“If we want to fight and be a contender, we need to talk on the pitch and not outside. We need to show we are capable after 10 months, not only after three games.

Just like Spurs, early season surprise packages Watford boast a 100 per cent record following three successive wins to kick off their season.

“We are going to play a very good team,” he added. “They are over the moon. It will be difficult. They have some very good players.

“If we are not ready, with everything being fantastic after beating Manchester United, then we will crash.”

Spurs, who remain homeless as their new stadium is still not complete, also have two cup competitions to contend with.

A tough Champions League group including Barcelona and Inter Milan awaits.

But there is also the controversial move of their Carabao Cup third round tie with Watford to Stadium MK as Wembley, their temporary home, is unavailable next month.

Spurs have asked for special dispensation to stage because their new stadium opening has been delayed by problems with the safety systems.

The Tottenham Hotspur Supporters’ Trust have issued a statement saying they will not attend the game.

“You cannot make all the people happy,” said Pochettino. "Maybe someone complain and create a big noise. The most important is the decision of the Football League is to us to pick the venue.

“We are going to make a decision and the best for the team. But of course we need to take a decision. The circumstances are so difficult. Our idea was the stadium was done for these days, but it’s impossible. Wembley is of course, it’s so difficult it’s a situation you cannot change.

“Of course it’s very difficult for us. The problem is for us, it’s not for our opponent. We are more disappointed than everyone. For our fans it’s to try to understand the circumstances of the club. What can we do? It’s not ready the stadium.

“We need to be patient and understand that the club is doing every it can to finish the stadium and have everything ready to compete there. It’s easy today to complain, it’s easy to agree or disagree. But for our board and our chairman, it’s so complicated."
