Thierry Henry is frustrated by lengthy VAR decisions he believes are draining the "joy" from football.
The World Cup winner is not against the technology, but is concerned by how the speed of reviews affects the matchday experience for fans and players alike.
Ireland supporters will never forget Henry's handball for France in 2009 in a World Cup play-off in Paris that allowed him to set up what proved to be a decisive extra-time goal for William Gallas.
Arsenal's record goalscorer was retired by the time VAR was introduced for the 2019/2020 Premier League season and agreed there’s still a gulf between current practice and potential when it comes to the technology.
"In football we’re still behind, we have so much to learn," he said. "What I can see in American football, in rugby, in cricket or whatever it is, tennis, it’s instant.
"We also know that the referee will give you an explanation, they have a microphone, they talk. Obviously in tennis, are you going to battle with the decision of the computer? If you start to do that, then you’re in trouble.
"With VAR, what I get annoyed with is it’s not quick enough. Then it’s still the decision of someone in a truck or wherever they are, because it’s not VAR that makes the decision, VAR is just there to recall the situation.
"And then the man in the truck will call to the referee to say you made a mistake or you didn’t make a mistake. Sometimes they help, yes, sometimes they help, no, but I can also understand that a human being can make a mistake.
"[Semi-automated offside] in the Champions League, for me, as long as it’s quick, as long as it’s quick and we have an explanation, I can see that the player was offside, you move on.
"What’s annoying is when you get lost in translation, when someone tells you something, another one, the rule changes the week after, it can become tough. We have a lot to learn in football."
Henry was speaking at the Leaders Week sport business conference at Twickenham Stadium, reflecting on a prolific career that included 228 goals for the Gunners in all competitions.
He joked he was a vocal player and would have "complained about the grass, the wind, myself, the coach, the weather, even if there was a computer, I would have said it’s lying".
Still, as an observer of the modern game, Henry was vocal in his frustration about video reviews that seemed to suck any momentum out of the sport.
"What we want to see is the game going on," he said. "Another thing that’s very difficult for me is I used to score goals as a player. Sometimes [now] you don’t even know if you need to jump.
"Am I jumping? Am I celebrating? Am I not celebrating? It kills the beat of the joy of the game."
