Italian refereeing supremo Pierlugi Collina on Monday threw his weight behind UEFA chief Michel Platini's idea of having two extra officials help refs with tough decisions in the penalty box.
Speaking after another rash of controversial weekend decisions heaped pressure on Italian refs, the former super-ref said the two new assistants would be especially handy for ruling on penalties and often-unseen fouls like shirt-pulling.
As well as a sharp pair of eyes for seeing whether balls have crossed the goal-line or not, Collina stressed the assistants would have to have ''great experience'' in making tough calls.
Among Sunday's most discussed incidents was a penalty that turned out to be a match winner for runaway Serie A leaders Inter Milan.
Video replays appeared to show the ball hit the defender's ear and not, as the referee thought, his raised hand.
Platini has said UEFA will shortly test out penalty-box assistants, both behind the goal-line and actually inside the box.
They would be just like the two linesmen who currently rule on offside, talking to the ref through a radio system.
Collina, who refereed the 1999 European Cup Final and the 2002 World Cup Final, was voted world's best ref six times.
He is now the selector of referees for Serie A and B matches as well as the Italian Cup.
