There has been a lot said recently about certain players not giving their all for the club they represent when they get on the pitch. And whilst this is true of many it is quite easy to understand just why a player, any player, might do this.
Imagine, you've been working tirelessly on your game: your fitness is absolutely top-notch and you, your team mates and manager, have all worked hard in training in order to give 100% at your next game - and then var comes along and undoes all your good work because a player's thumb was in an offside position. You are going to feel pretty pissed off, understandably. And then a few moments later an opposition player throws himself theatrically to the ground in your penalty area with no contact from anyone and var says it's a penalty. You and your team walk away from a game knowing you didn't lose to a better team, with better players and superior tactics, no, you lost the match to either incompetence and/or corruption.
Then in the next days' media you are being ripped to shreds by people like Garth Crooks and Glenn Hoddle for not doing your best.
As with most people, I believe var in football should be used exactly the same way as at is in rugby: open and above board and ref's mic'd up so everyone knows exactly what is happening and why. And if those at pigmol or var say no they should have to come out and explain precisely why.
