If Celtic play their best, they could score 5 or 6. It's no coincidence, however, that when we have been beating teams like Aberdeen or Rangers the match reports are full of how bad they were. We have players and tactics that make good teams struggle.
We are rightly the underdogs, but I can't imagine many pundits thought Scotland would score 53 points against the Australians today. That's the beauty of sport - you always have a chance.
