That happened last night in the Argentina-Greece game that I watched. Argentina went up 1-0 with 10 minutes left. They went into keep-away mode. On a field that big with that many players on it, it worked pretty well. They would gradually move the ball up-field, then kick it way back to their own end, wash, rinse, repeat.
With 10 minutes left up 1-0, the commentator was already saying it was over.
