The Argentine spent five-and-a-half years in charge at Spurs before being dismissed and replaced by Jose Mourinho in November 2019.
That eventful period saw the club transformed into title contenders, reach a Champions League Final and also swap the old White Hart Lane for the plush new Tottenham Hotspur Stadium via a lengthy stint at Wembley.
And while Tottenham ultimately never managed to end their silverware drought under Pochettino, the 47-year-old - who has signalled his desire to return to the Premier League - insists factors such as the new ground, multiple seasons in Europe's Premier club competition and finishing above north London rivals Arsenal on several occasions give him a lasting sense of pride.
"Of course I feel very proud about everything I achieved at Tottenham and when I analyse my time there, plenty of positive things happened," he told Sky Sports' In The Pink podcast. "I took charge at a pivotal moment for the club.
"Everything I had to do was very scary in those moments. To destroy White Hart Lane and to build a new stadium, to play at Wembley and Milton Keynes, only football people know how difficult it was to deal with these situations.
"To apply a new philosophy and new ideas was very tough but I feel very proud with the success that we had and to take Tottenham to a different level.
"To play in the Champions League for three or four years and finish above Arsenal many times was a great legacy for us.
"To win a title would be a great reward but for us that is the legacy, to have the club and the stadium at Tottenham.
"That is more than winning titles."
