The Argentine watched from the sidelines as Harry Winks marked his first Premier League start with his first goal in Spurs colours, as a dramatic derby turned on its head courtesy of Harry Kane's two late goals in a 3-2 win against West Ham United.
Winks, who was superb throughout the match, celebrated his strike by running into the arms of Pochettino who recognised it as a very special moment for the 20-year-old midfielder.
Asked about Winks' equaliser, Pochettino told the website: “Brilliant, brilliant. It was an emotional moment for him and for us because after two-and-a-half years working here, we believe in him and it’s fantastic.
"[Saturday], he paid it all back. The players coming through the academy show passion and that is our identity. It’s fantastic when you can see Harry Winks scored and needed to cry, needed to cry after in the changing room."
Winks is regarded as an exciting prospect at White Hart Lane, with Pochettino showing his faith in the young Englishman by handing him his first start in what always has the potential to be a competitive and feisty fixture.
Yet he held his own, becoming one of Spurs' better performers in an unconvincing win that suggests he may have kept his place for Tuesday's crucial Champions League clash with Monaco.
Tottenham have never been afraid to blood youngsters from the academy through to the first-team and Pochettino was eager to applaud the coaching staff for their work in developing the would-be Spurs stars of the future.
“We also have to recognise all the people in the academy – many coaches, many people working for that dream of all players," he added.
“It’s a priceless moment and we need to create more and push more in the future. We need to congratulate the people in the academy because the work they are doing is fantastic from a long time ago.
"Maybe not all the players have the quality to play but if they have the quality, why not give them the opportunity to play?
"It’s fantastic because at Tottenham it’s not just about bringing players from all countries or leagues, it’s important to give the opportunity to our youngsters too.”
