After watching Colombia display some of the worst cheating I've seen in a while I was surprised to see comments from Falcao and Maradona saying that they thought the ref was biased towards England. I thought the ref had a difficult game and did make some mistakes but actually was lenient towards Colombia. He should have sent that guy off who headbutted Henderson for a start. VAR also failed in that instance. What's the point in VAR if the officials are still scared to implement it. Since when did headbutts become yellow cards?
