The Spurs legend thinks the boss needs time to deliver.
Pochettino was handed a five-year deal in the summer with the aim of returning Spurs to Europe's premier competition - following on from a disappointing season where Spurs finished sixth in the Premier League.
The side have made an indifferent start to the season by picking up seven points from their opening five games, got a solid point in the Europa League group stage opener in Belgrade against Partizan, and have made it through to the fourth round of the League Cup.
Ardiles told TalkSport: "He’s the right man for the job.
“His ideas are very clear. He believes in putting a lot of pressure on the opposition, pressing as high as possible, recovering the ball quickly and then playing.
“Of course it’s not going to happen overnight. He’s got a big job on his hands and I just hope he gets given time.
“Tottenham have changed managers too many time, they need to stick with one.
“In Mauricio they have someone who has the right ideas. Hopefully he will do the job for us.”
The length of the deal given to the Argentine indicates that he will be afforded a substantial amount of time in order to achieve their aims and objectives.
Spurs were accused of being hasty in their sacking of both Andre Villas-Boas and Tim Sherwood last season, and not giving them enough time given the amount of money spent and the amount of players that arrived at the club.
Pochettino has made his own additions on top of that, and is seemingly trying to integrate some of the players bought last summer into the side as well. They will at least be expecting signs of improvement and good form as the season continues, and as players adapt more to the Argentine's style of play.
