The referee consults VAR before it is decided that Harrison McGahey was unfairly challenged just before the strike.
"The system didn't help, the spectacle, it was a little bit embarrassing". He said: "Cut out the sideshows and make sure we focus on trying to to win the match".
"That's why the referee should be the boss on the pitch and have the last word - always". Erik Lamela cleaned up the offering by putting it in the net. There were jeers during the lengthy stoppages when referee Paul Tierney chose to halt play and put his finger to his ear.
However Tierney, on the advice of the VAR, ruled it out, seemingly because of slight contact made by Fernando Llorente with a Rochdale defender in the build up. The original decision stands. VAR drained the match of all flow, fluidity and continuity, akin to the effect of aspiration on a swollen, fluid-filled knee.
Rochdale's Ian Henderson has been the star turn in their cup run with six goals in the tournament so far - only Will Grigg with seven has more.
45+5: Lamela challenges Callum Camps, which prompts Tierney to hand him a yellow. The goal is awarded.
"I think we have the best referees in Europe and the world".
Fans were even more angry.
Rochdale have their injury concerns too, with Niall Canavan, Keith Keane, Steve Davies and Calvin Andrew all ruled out for the side through respective injuries. There have been suggestions VAR could be deployed at this year's World Cup in Russian Federation but Pochettino insisted: "I think football is about to make a mistake".
Meanwhile, Pochettino has scoffed at suggestions Tottenham could have an unfair advantage should they reach the semi-finals of the cup as they will be playing at their temporary Wembley home. That, more than anything, is what annoyed Danny Rose, and appears to be the biggest hurdle that the technology has to overcome to make it an accepted part of the game in England. Why are we hiding the decision? You have to embrace it, take a leaf out of rugby.

"Then the offer of a move to Rochdale came up last month and I have come in here feeling like I know what is expected of me this time".
Mark Schwarzer on BBC Radio 5 live: "Human error will still occur with VAR, other sports have shown that, but it dramatically reduces the number of errors".
Nevertheless, the Argentine expressed the significance of the cup to the club, explaining: "It's an important game for us".
Tottenham face League One Rochdale in their fifth-round replay on Wednesday evening and the Premier League giants confirmed the match would go ahead despite some adverse weather. Why can't we copy the rugby and the cricket?
"It leads to so much confusion and is definitely not good for the game".
Arguably, the one moment that did need video evidence was the goal for Llorente immediately after the restart. "I do think it will improve".
Walker-Peters, who got himself a keepsake to treasure when he scored in stoppage time. Goals: Son 23, 65, Llorente 47, 53, 59. I love football as football was born. Don't underestimate the damage this does to the game.
"When you tear a muscle, then you are fit but fit to participate in training. But we're in good form and we need to keep this".
The controversial decisions left Pochettino livid.
"However, when it comes to the hairline decisions it can end up just slowing the game right down".
It nearly got worse for the League One strugglers as they watched Lamela's free-kick come off the upright. Why don't they learn from rugby union who have the system spot on and everybody knows what is happening! "It is what it is and we just have to get on with it". What's the point of paying to be at the game when you have no clue what's going on?
