Press ‘play’ now on video refs
His priority was to be level with the last defender, checking for offside. Carl Lewis wouldn't have made it back in time to see if the ball was over the line. Nor was the referee at fault. Anyone who has ever watched a game at pitch level should understand how difficult it would be to judge where Roy Carroll's fumble ended up.
Nor do I agree with the naive who suggest the Manchester United goalkeeper should have 'owned up' to his error: "Look ref, mea culpa, egg on face, it's a goal for Spurs"
