Looked like a clear deflection off the Cardiff player after leaving Styles's boot. It was on that side where the linesman was so he has no excuse for not seeing that. Surely the referee should have had a chat with the linesman before making a final decision. Just to chalk off such an important goal without any consultation makes it all seem so much worse. A point was still not enough for us, but better than no points at all.
Even if you pause it when he receives the ball, he's still not offside, it's as clear as owt (to me anyway, but i know nowt)
