The Southampton boss is to be given a three year contract, and he needs to be given those three years at least.
But with Chairman Daniel Levy’s record when it comes to sacking managers, hitting the ground running for the 42-year-old Argentinian is going to be vital if he is to be a success in North London, as qualification for the Champions League will inevitably be the target.
Pochettino has developed a reputation for high tempo, pressing, attacking football whilst trying to establish a solid defence at Southampton, and has taken the club up another level from the tenure of Nigel Adkins.
With so many players joining Spurs last season and seemingly a disappointment, the Argentine is going to need to be given time in order to get the best out of his squad – which something that a lot will say the Spurs chairman isn’t renowned for.
Changing the style of play is going to take time, no matter how different it may be as the manager tries to get his own ideas and philosophy across.
He may be a manager who is more inclined to tap into the youth set-up than most given the chances he has given to youngsters at St Mary's during his time on the South coast, which will probably please both the hierachy and the fans.
He also seems full of ideas, won a lot of praise for the work he did at Espanyol, none more so than across the city of Barcelona at the Nou Camp from Pep Guardiola, a ringing endorsement indeed.
Former midfielder David Ginola has said that the club needs some stability over whichever new manager comes in, and needs a sustained period of time to try and build something at the club.
In Pochettino, Spurs will have a manager with a positive mentality who doesn't seem to fear opponents, and will take the game to them. He also has much to learn, therefore if he makes a mistake he should be given time to rectify it. Sacking managers has not done Spurs too much good - Harry Redknapp being a notable exception, who was then sacked himself, but in the season just gone the same problems occurred under two different mangers.
When they conceded goals to sides near the top, they conceded several, and there were some unconvincing displays against other sides in the league. There will probably still be those games in the first season, but if there is a clear vision, and sense to what the new boss is trying to do, then they should allow Pochettino to continue to implement his ideas and not press the panic button.
There's a chance here for both the team and manager to evolve, and even if there are bumps along the way, they should keep the faith.
