Biraz isn't phased because he is better than our tinpot club, destined for greatness and let down by the shambolic play of 7 or so people in front of him.
BK cares because he knows that being a second choice keeper at the shittest club in the league is his greatest ever achievement and it really hurts when he sometimes gets dropped to youth to watch goals get pinged in from 40m without moving a muscle.
