The problem is that take yesterday's game for example. The car operator wasn't a video technician able to bring up the correct footage for the ref to view it was international ref Darren England and as soon as he says to the ref I, as one of the countries top officials, think you've got this wrong mate then it's very very hard to say fèck off Darren I'm sticking to my decision. It would be career suicide. There's absolutely no reason for a referee to be involved with var at all. The ref on the pitch is the only one who's opinion matters, anyone in the back room should simply be there to bring up video clips
