His side progressed on away goals after their tie with Manchester City ended 4-4 on aggregate.
The thrilling second leg at the Etihad Stadium finished 4-3 to City and the home side had a goal chalked off in the final minutes through VAR, meaning Pochettino’s side went through.
Spurs had to do it without star striker Harry Kane, who was injured in the first leg.
Pochettino was clearly pumped up after the miraculous game and a video has been posted on Twitter that shows the Tottenham manager copying the Diego Simeone crotch-grabbing celebration.
He then slaps a whiteboard while the players celebrate in the changing room.
Simone did the celebration after Atletico Madrid’s opening goal against Juventus in the first leg of their last-16 tie in February.
He did it to show his team have ‘balls’ and they went on to win that match 2-0.
They could not progress to the next stage of the competition, though, as a Cristiano Ronaldo hat-trick saw Juve make a brilliant comeback.
