I always enjoy how its lucky when Lloris makes great saves to win us games but not lucky when Aguero or whoever scores great goals to win games for their team. I feel that performances of keepers are too often seen as separate from the rest of the 'team performance' - that a good goalie winning games is lucky, whereas a top goalscorer winning games is down to ability. Maybe there is a lack of understanding from most in the media about how difficult it is to be consistently a top goalkeeper, I don't know.
And as SD said, consistently scoring late goals is nothing to do with luck - its fitness, desire and ability that gets you consistently threatening to score in the last 20 minutes, not luck.
