Chelsea will experience goal-line technology in the Club World Cup.
"I don't like video technology during the game," said Benitez. "You can change too many things and then you lose something. I remember a final in rugby where there was three minutes to make a decision with the technology. Three minutes!
"There was a penalty against us and we can see four replays. In three it was a penalty. The fourth, he didn't touch him. Who will analyse this? How long will it take to analyse every single angle?
"Goal-line technology is different. It's a crucial decision for a game. If you have the technology and you can guarantee it is fine then you have to see it."
