Tottenham have been transformed into genuine Premier League title contenders under the Argentine.
Indeed they have established themselves among the European elite this season with the 3-1 win over Real Madrid evidence that Pochettino's Spurs have really arrived.
With Tottenham's success has come the inevitable speculation over the future of star players such as Harry Kane and Pochettino himself.
Talk of interest from the likes of Real Madrid has some Spurs fans understandably concerned.
But the majority of supporters feel certain Pochettino is in it for the long haul given what can be achieved at the club and the fact he has built a young team from the ground up.
However, Spanish football expert Guillem Balague - who was the ghost writer for Pochettino's book Brave New World: Inside Pochettino's Spurs - has suggested on Sky Sports' The Debate that may not be the case given the huge emotional investment the Argentine puts into his work each day.
"The things that annoys everybody at Spurs is that after a good performance the headlines is like 'Harry Kane will he now go to Madrid, or Pochettino will he now go'," Balague said on The Debate.
"They are giving absolutely everything to this, him and Jesus and Mickey and Tony of course and everybody involved.
"With that at the end of the day they go (sits back, closes eyes and puffs out his cheeks) 'Yes we've given it everything' and they give that everyday to build success.
"I'm sure at some point it will be like you're seeing with (Diego) Simeone and Atletico Madrid, it's like 'Oh God another year of Simeone (and that intensity)' for the players just not being able to give any more, it may happen absolutely (with Pochettino at Spurs) and the other way around as well because he's investing so much emotionally Pochettino, endless, that he may be tired at some point."
