The 41-year-old Saints boss has revealed Tottenham have not contacted him about replacing sacked manager Andre Villas-Boas.
The former Argentina defender poured scorn over speculation linking him with a move to White Hart Lane, by praising Saints chairman Nicola Cortese's staunch backing.
Question marks have been raised in the wake of Villas-Boas' departure as to where the recruitment power lies at Tottenham.
Former Chelsea boss Villas-Boas long championed a technical director for Spurs and got his wish when Italian Franco Baldini arrived from Roma in June.
However noises around Villas-Boas have started to suggest Baldini held greater sway than the now-unseated manager.
Pochettino said he would not want to work in a set-up where board-level decisions conflicted with managerial vision.
Southampton host Tottenham at St Mary's Stadium in Barclays Premier League action on Sunday, seven days after the 5-0 home humiliation by Liverpool that led to Villas-Boas' removal.
Coach Tim Sherwood will be in the Spurs' dugout.
"We have a very good working relationship with the chairman, we decide together as a team, even within, what players get signed," Pochettino said.
"And it's always the okay of the manager that makes it go ahead.
"It's clear as well that new players to this league need time to adapt.
"In our case Lovren, Wanyama and Osvaldo have different times to establish themselves and adapt to this league.
"It's easier for three players to adapt than 10 in Tottenham's case, but new players need patience and some of them need longer than others."
Pochettino said he is not in talks to extend his Southampton contract, that expires in summer 2015, but is happy with his lot at St Mary's Stadium.
"I have until next season, but we have not spoken about it yet," he said.
"It's not up to me, it's not my decision.
"I have a contract until the end of next season, and at the moment we're fully focused on the game ahead, nothing else."
Pochettino refused to allow speculation linking him with Tottenham to act as any kind of vindication of progress at Southampton.
He said: "It has absolutely no effect on me, neither in a positive nor a negative way.
"First of all I don't read any press, or very little, and it's something that I don't need.
"I don't need to be flattered in order to confirm the good work that we're doing here.
"We know that we're doing a good job here, that we have a good team that's playing the way we want it to play.
"And it's not something that I need to confirm the work that we're doing here."
Pochettino admitted the jury is still out on an appeal against the violent conduct charge the Football Association have levelled at striker Dani Osvaldo.
Osvaldo was hit with the charge after a touchline rumpus at St James' Park last weekend when Southampton held Newcastle to a 1-1 draw.
He said: "We're analysing the situation, we're studying the situation.
"We have until December 23 to make a decision to appeal.
"There's a process: he's been charged by the FA, we've reviewed the images and there's nothing clear from the images from our point of view.
"And I think it's all a bit confusing at the moment."
