It's a nice idea, but as the Juve/Torino derby fiasco recently showed, the system will still be at the mercy of the pig headed officials involved. In case you missed it, Juve scored, Torino objected because there had been a clear foul in the build up, the ref reviewed it on the VAR and, despite the aforementioned foul having been absolutely blatant, incredibly decided to uphold his original decision to give a goal. As we've also seen with the Lukaku 'kick in the cobblers' non-ban, the VAR will be a waste of time, because it will be open to ridiculous interpretation. Last minute at the Swamp, Aguero gets scythed down by De Gea in the box, and City play their appeal. Can you honestly see Madley, Taylor, Jones et al, awarding us a penalty on review? Not a chance
