Sir Alex Ferguson has claimed “the time is now” for some kind of additional assistance to be given to referees.
Ferguson was at the Emirates Stadium on Wednesday as Arsenal eased their way into the Champions League group stage by overcoming Celtic.
Yet the Gunners' victory was overshadowed by the antics of striker Eduardo, who appeared to throw himself to the ground in winning a penalty.
Although Spanish referee Manuel Gonzalez was duped at the time, TV replays proved Eduardo had not been touched.
“For the last decade there has just been talk. Nothing has been done,” said Ferguson. “The time is now. Michel Platini has his own views about bringing in extra human assistance with additional referees and assistants but most people in the game think technology should be used.
“Whatever the debate it should lead to something more positive in terms of helping referees in situations like Wednesday night.”
