The Barbecue Ghost really did a runner on the assistant official, and even though I haven't seen it yet, the goal was totally offside. Either way, Chelsea still won by two clear goals and no-one likes Reading so it doesn't matter. Gary Cahill even admitted that luck was on their side:
"It was maybe slightly [offside] so that went for us"And he looks like he was built from the discarded and broken parts of Robo Cop. He's like the plain clothes figurine that no-one wanted because his special function was like 'lifting a suitcase' or something.
