The system was used three times during Spurs 6-1 win over Rochdale in the FA Cup on Wednesday night, causing five minutes to be added in stoppage-time.
And speaking after the game, the Welshman went to town on the use of technology in football.
Speaking on The Debate, the former Wales striker said: "It was laughable. It was a disaster.
"The Liverpool game stands out as well. I've watched games in Germany and Italy where it has been a farce. It really has because the supporters don't know what's happening. They're all standing around, waiting minute on minute and the players are having to do extra warm-ups. It's just taking so long.
"Were the refereeing decisions in our game so bad that we have to get everything right? As a manager, as coaches and as players we are not going to get everything right. It's impossible because we make loads of mistakes on the pitch. We like to think we don't, but we do.
"Referees are exactly the same," he added. "They will make mistakes because they are human and human error in our game is brilliant, it's not a problem.
"Of course it's not nice when it's cost you a result, but that's the part of the game I really love. I like being sat there in the crowd sometimes when it should have been offside, but it's not and the referee has let play go on and there's a goal and the team have got away with it.
"That's the part of the game I really enjoy and if we are going to try and take that out it's something I'm not comfortable with. It's something I've never been comfortable with and it's something I really don't want to see in our game."
