The challenge by Brighton’s keeper Robert Sanchez on Liverpool’s Luis Diaz as the Colombian striker headed in the opening goal at the Amex Stadium is one, like many, that will provoke debate.
Had match referee Mike Dean shown Sanchez a red card, I’m not sure that decision would have been overturned as it is a subjective one.
If Sanchez would have gone in for the challenge with studs showing and/or made contact with Diaz’s head, the VAR, in this case Stuart Attwell, would have had the evidence to advise showing a red card.
