Pochettino has enjoyed a successful stint at Tottenham since his arrival from Southampton two-and-a-half years ago.
The Argentine boss steered the club to a third-place finish in the Premier League last season and has them second – behind leaders Chelsea – this term.
Spurs face Manchester City on Saturday seeking an eighth straight win in all competitions.
They have locked key members of their current squad down to long-term contracts and are building a 61,000-seater stadium ready for the 2018/19 campaign.

We maybe could be here for 20 years
And Pochettino says is not looking to use the club as a springboard to landing another job elsewhere.
“I am very happy (in England),” he said.
“It’s true that we are me and my staff are very well here. It was fantastic after a good and not so good experience in Spain as a coach.
“We’ve fit in fantastically since day one in England.

“It’s true that it’s only four years (since I arrived from Southampton) but we maybe could be here for 20 years.
“Why not? I’m not a person thinking 10 years ahead. I try to focus on today and try to work for tomorrow to be better.
“With that philosophy I’ve spent four years here and it would be fantastic to spend more time.”
Pochettino was linked to the Manchester United job last year during Louis van Gaal’s final days at the club – but Jose Mourinho eventually landed the post at Old Trafford.
There have been reports linking the former Espanyol boss with moves back to Spain – namely to Barcelona or Real Madrid – in the future.

But Pochettino insists his sole focus is on Spurs.
“We are ambitions and want to win every game,” he said.
“If we go backwards for a season from what we were, that would be 1000 miles. Football is about belief, faith and working hard.
“In two-and-a-half years (we have met) our expectations. Not to push and move the club quick – sometimes that is not possible. But it relates to excitement around Tottenham. The new stadium, the team.
“Today it looks like we’re the best team in the world. That is very good. The aim is to keep that feeling.”
