There's an article by Keith Hackett in todays Torygraph
Some excerpts:-
......VAR clearly isn’t the solution to all our problems if used incorrectly, as was the case at Molineux. The issue here was a sliding challenge by Manchester United centre-half Victor Lindelof on Wolves’ Diogo Jota as he broke away down the wing. It was a poor tackle and Martin Atkinson, a very experienced referee, deemed it worthy of a red card. That decision was downgraded to a yellow card by the official behind the TV screen, who on this occasion was Kavanagh - a man who had to referee his own game at the Den a little more than 15 hours later.
I think Martin got the call right, and I cannot see how Kavanagh overruled him. Law 12 states a red card must be shown “when a player exceeds the necessary use of force and/or endangers the safety of an opponent”, which I thought Lindelof did. We must also remember that VAR should only be used to overturn “clear and obvious errors” and I do not see how Martin’s decision was in any way a clear and obvious error..
Totally with Keith Hackett on this one. Lindelof went right through the player to get the ball. A modern day, text book red card. On Twitter he's been making the point that because we're not giving the ref a pitch-side monitor here, you've got far less experienced officials over-ruling some of the very best we've got (which is not saying much at the moment, sadly). I hate the way the pitch-side monitor brings everything to a halt - but I can see his point. That's a problem.
