This is not an argument to keep it though, yes we were all delighted it was disallowed, but had the linesman not had the fall back of var he may have flagged, he may not have, had it stood we may or may not have gone on to win the game.
However whatever the decision would have been us or chelsea would have had to suck it up, we’d have gone home and got on with our lives, it wouldn’t have caused any real controversy as the call was so close.
