Spurs have not won the top-flight title since 1961 and their last trophy was the 2008 League Cup but Pochettino insists only Premier League or Champions League trophies will take the club to the next level.
"If my ambition in Tottenham is only to win the Carabao Cup or FA Cup, with all the respect for that, I think my ambition does not match the ambition of a club like Tottenham," he told reporters on Thursday.
"My ambition is to win the Champions League one day with Tottenham or the Premier League."
Pochettino has led Spurs to three consecutive top-three finishes in the league, despite operating with a tight salary structure and transfer spending.

Revenue from regular Champions League qualification is critical for Spurs' financial stability as they prepare to move to their new 62,000-seater stadium.
"In some clubs, if you don't win a trophy, you fail. But in our project at Tottenham we are completely different... we have bigger things than to focus only to win a trophy," Pochettino added.
"But that doesn't mean that we are not focused on trying to win against Chelsea in the Carabao Cup or in the FA Cup. But you need a lot of coincidences to win sometimes."
