i think you can debate the decision all day long, I have seen it three times outside of the game and still unsure. Bit more than a Yellow and not quite a red (orange card??). The whole thing was a farce, Millwall and Swansea didn't have it and Wolves and Watford had it?! All of which had some decisions that would have been altered by VAR (not sure about Watford as I didn't watch it). If we cannot be consistent then you have to turn it off for all, it would be like removing penalties in one game and not the other?!
I have never been a fan, don't like that teams cannot celebrate a goal before being validated by VAR as the ref seems to overly nervous to make a decision by himself (don't blame them to be honest), I don't like the delays and the fact that it now seems to be the choice for everything rather than key decisions. Its only going to get worse.
