Aston Villa boss Martin O'Neill believes it is inevitable video technology will be introduced into football after his side benefited from the kind of contentious decision which would come under scrutiny.
Villa remain in the hunt for a Champions League spot after James Milner's spot-kick earned them victory over local rivals Birmingham at Villa Park on Sunday lunchtime. But Blues boss Alex McLeish was incensed by the decision of referee Martin Atkinson to award a spot-kick for a challenge by Roger Johnson on Gabriel Agbonlahor.
He said: "Should video technology come in? You may well have a point. I'm sure at some stage in the next couple of years it will probably come in - and I'm quite sure I would welcome that."
He added: "If Rugby League can make decisions on tries, and it doesn't disrupt the game phenomenally, then I think it is worth a shout in football."
McLeish is more in favour of the extra officials that have been trialled in the Europa League this season.
He said: "How far do you go with video technology but (UEFA president) Michel Platini's methods would have worked with in this case, the fifth and sixth officials.
"They would have seen Roger got the touch on the ball."
Villa are level on points with fourth-placed Tottenham and now face a trip to Manchester City and their former skipper Gareth Barry next weekend.
O'Neill said: "Have we a fighting chance of the Champions League? It has been a great week for us (nine points from three games) and the consequence of winning against Birmingham is that we have qualified for Europe (Europa League).
"Now we can go into these last two league games giving it everything. Manchester City will be exceptionally hard but we are going to have to try and win."
