Manchester United boss Sir Alex Ferguson was amongst the head coaches given a presentation on goal-line technology by referees' chief Mike Riley at the first Castrol/LMA European managers and head coaches forum held at the national football centre at St George's Park. But Ferguson was wary of going down a route that would see the game suffer interruptions.
He added: "You've got to be careful with how far you go with technology. I think that the basic progress we have to see is the goal-line technology. That's a simple one-off situation and it was explained by Mike that it can be done very quickly.
"But because we are a winter game, unfortunately, it means then that you don't want to have supporters sitting there, inactive in terms of their involvement watching the game, waiting for a decision, whether it's by an assistant or someone looking at a television screen.
"That has got to be 'puff' [claps hands] decision taken and move on.
"It could happen maybe three, four times in a game you see. So, you don't want two minutes, three minutes each time the game's stopped. People could go to a game at 8 o'clock on a Wednesday night and maybe not get home till midnight."
