So far so good, but they maybe should have hired a better driver, because the person behind the wheel of this one made a grave navigational error. The bus was accidentally driven into a Manchester United fan zone, where a bunch of fans were at the pub drowning their sorrows.
Unsurprisingly, the United fans didn't take well to the sight of a Chelsea bus, and they lobbed whatever they had to hand.
