Birmingham manager Alex McLeish has called for the additional officials being experimented with in the Europa League this season to be used in other competitions.
McLeish witnessed the crucial handball by France's Thierry Henry against the Republic of Ireland in the World Cup qualifier in Paris which resulted in William Gallas' goal which put the hosts through to South Africa.
McLeish said: "The ref never saw it (the Henry handball) so it is one of those things that happens in football but I think it increases the demand for technology - and even the experiment they are using in the Europa League with the fifth official."
He added: "He would have seen that (handball) given that the referee's assistant on the far side didn't really have a view of it and the referee was unsighted."
McLeish also saw his side denied a possible win against Liverpool at Anfield 10 days ago after a disputed penalty was awarded following an alleged dive by Liverpool's David Ngog.
He added: "It was a little bit like the incident at Liverpool when we lost the penalty. The referee is unsighted and gave what he thought was a penalty but he couldn't be 100% sure.
"But when 40,000 Anfield fans scream for it then he says 'it must be'. A fifth official would have spotted that was a dive (by Ngog)."
However, McLeish believes it is unfair to brand former Arsenal player Henry a cheat.
He said: "I would never say Thierry Henry was a cheat. He has been a fantastic ambassador for football. It looked instinctive. It hit his arm and then it looked as if he cupped the ball before it went out of play but it is a split- second reaction by a human being.
"I wouldn't say Henry is a cheat but it has been missed and it has cost Ireland a possible place in the World Cup finals."
