Brian Kerr and Damien Delaney clashed on Wednesday's night's Virgin Media coverage after Real Madrid dumped Man City out of the tournament.
Man City looked poised to make a consecutive Champions League final as the led 5-3 on aggregate going into injury time.
But two late Rodrygo goals forced extra time and a Karim Benzema penalty sent Pep Guardiola's side crashing out.
And pundits for Virgin Media on the night Damien Delaney and Brian Kerr disagreed after the late drama.
Delaney took the side that it wasn't a complete collapse from Man City and they were simply unlucky while Kerr took aim at Jack Grealish in the build up to the second goal.
Speaking at full time, Delaney said: "You look at two goals, nobody does anything wrong. Rodrygo somehow gets his head on a flick on from his own player... it gets flicked onto his head."
But Kerr took exception, saying: "I'm not so sure nobody did anything wrong. The centre of the box, maybe not but allowing the cross in. Grealish backed off and allowed the cross."
Delaney took exception as the pair debated over Grealish and as the two reviewed Madrid's first goal, Delaney said: "Hang on a second, Cancelo is taking the position inside because there are three Real Madrid players. He drops a touch early and the ball is helped at the back stick. It's a good goal.
"Of course you can pick the bones out of it and say Man City in an ideal world would have done different things but there was catastrophic collapse, it was just a well worked goal."
