He was trying to shield it?
He literally just got hold of it. Doubt it was shielding.
You've already admitted your a Leeds fan, so your blinkered in what you would dish out. Alioski raises his hands and pushes the assistant, and you'd give a yellow? Canos comes in and uses his forehead, softly, in the back of the player whilst he is shoving the assistant, red? So if he came in identically, shoving him, would you change your mind and only give a yellow?
I could understand if Canos forcefully uses his head and goes to intentionally hurt Alioski but he done neither.
Not sure what laws of the game Leeds follow but if your sending off Canos, your sending off Alioski.
Personally think it's more handbags. But given what I've seen on social media, Leeds fans want blood and are upset that they could not win against Brentford and are now going for the referee as it's his fault and not their players for scoring more than 1 goal in 90 minutes.
