Pochettino also expressed his pride at being the first Spurs manager to reach 200 games under chairman Daniel Levy in Wednesday's FA Cup win over Newport. And he said he had no idea how difficult the project would be when he accepted the job in May 2014.
On being told he was the longest-serving Tottenham manager since Keith Burkinshaw, Pochettino said: "That makes me proud that the board and Daniel Levy showed the confidence and trust.
"When I arrived, I didn't realise everything from the beginning but then I soon understood that we arrived at an amazing club, with an amazing history, amazing fans.
"We soon realised how difficult it was and what the process would be of moving from one stadium to another. We knew it was a difficult moment in terms of the whole process of the club but we went through with it."
