What advertising company made McDonald’s ad during the Olympics with those two boys soccer teams?

There was this nice commercial during the Olympics by McDonalds that showed 2 boys soccer teams, when the one team won they taunted the other losing team of boys until the losers got McDonalds food, then they shut up.
What advertising company made that commercial?

Most likely it was DDB in Chicago. McDonald's uses a lot of different ad agencies for regional spots across the country, but the national spots are usually done by other Leo Burnett in Chicago or DDB in Chicago.
