The VAR refs have to watch all the games as its their job to spot a possible mistake or something the on-field ref misses. For example the on field ref might not see a red card offence and so will have their attention drawn to it by the VAR ref.
A thought I had today. Once/if they get it right, how will it work on the last day of the season, for example. It wouldn't be fair if not all PL games had it but how will they do 10 matches at the same time. There are only so many refs available at one time to sit in front of the tv screens.
I would say footballers who exploit loop holes to pay less tax are better than the tens of thousands of plumbers, carpenters, electricians, window cleaners and all other trades people who defraud HMRC of VAT, Tax & NI on jobs where they are being paid in cash.
Darts - he throw a dart and scores 20, he throws a dart and scores 60, he throws a dart and scores 1, that's 81
Football - he kicks the ball, he heads the ball, one team attack, the other team attack and the other team score
Javelin - He runs up and throw the javelin, its landed 120 metres...
That's ok City will have won the league by then so will play their kids, although they would still have cost more than our squad, stadium, training ground and the combined wealth of our fanbase
