[Beefy 1965]

But at the moment they only review what the referee isn’t sure about and if he didn’t see the push on Barry, which I assume he didn’t then he was only asking for it to be used to check if it was offside or not, which it was.  Its not perfect but it will evolve and get better.

Yes but on reviewing the footage the first offence, the penalty, would have been seen ...... penalty.

...as in Rugby Union - the replay very often shows another infringement that wasn't originally identified. I really don't see why football can't just follow what RU do - the groundwork has been done, let's not reinvent the wheel.

Ok, but how far back do you go?  What if there was a foul before the ball reached the box, would that be counted?  There has to be a line drawn somewhere, in this case the ref wanted to know if a player was offside for the goal, he wasn’t asking about reviewing anything else as he didn’t see any other infringement during live play.

I agree St Charles
However it was a dead ball situation that need not go back in these circumstances, the "double" push happened seconds before the ball hit the back off the net,
Your right a line has to be drawn, but something that happened in the same picture frame is pretty damning and from that a penalty should surely have been awarded
