Mauricio Pochettino believes the implementation of VAR in the Premier League should be delayed as he fears English fans will be even more frustrated by it than those in other leagues.
Harry Kane's decisive penalty in the first leg of the Carabao Cup semifinal against Chelsea was awarded by the video review system, with Tottenham winning 1-0 at Wembley.
VAR will also be in use during Thursday's second leg at Stamford Bridge, and Pochettino is concerned about what will happen if it is introduced in the top flight next season as planned.
"For me, I think it's a good idea to delay," he said. "If we don't have all the information or don't know how it will work and don't work to develop better the system, it's better to stop for one year more. That's my opinion if people ask me.
"I don't know if Daniel [Levy, the chairman] will ask me, or the Premier League. But watching every single game in Europe now, no one's happy.
"That worries me a little bit, that there's going to be a situation where, rather than helping football, it's going to be annoying our fans. This business is so important and football fans must be happy. If you stop for five minutes, I don't know how they're going to behave.
"The Premier League today is the best spectacle, maybe with the NFL or NBA in America. I think in Europe or in football it's the best show, so we need to be careful how we develop this system and how we use it.
"Fans in Italy and Spain, if they're having problems, in England it's going to be worse.
"The dynamic of football is completely different. In Italy or Spain it's more about taking time to restart the game, but here the fans are used to play, transition, corner, goal, boom. It's instant."
Pochettino has bad memories of last season's FA Cup fifth-round replay against Rochdale at a snowy Wembley, when Spurs had a goal disallowed and then a penalty awarded, both by VAR, in the first half alone.
"There was an incident in the first half that took forever to decide," he said. "After the first half I think 10,000 [fans went] out! Whether you get the benefit or not, it's so strange. I think we're not ready to accept this type of situation.
"How the Premier League is today is fantastic, and goal-line technology is the best. But after that, it's about whether the referee sees the incident or not, interpretation. That's how we were taught to play football -- it's about how the referee perceives things. But now the interpretation and emotion isn't going to be there.
"Maybe technically it's a handball, but in football we know very well when it's not intentional and only the referee can see that, or the players that are around. Through the video you cannot perceive that. That's the dangerous things that I think are going to come here with VAR."
