Replays showed it was a corner. That was a good decision
Re: The lualua penalty.
He didn't really get it wrong, as such. Yes, it was a foul and he could have given the penalty, but he played the advantage as Lualua stayed on his feet and retained possession, Lualua then played a dangerous ball across the box and none of our players reacted well enough. Play is pulled back to the point of a foul if there is no advantage, not if you squander the advantage you had.
Fair enough, i was on the other side of the pitch.
