It was not me, by the way, rather a game-friend of mine who suffered the heavy defeat,
I was browsing the results and the number "21" caught my attention. At first I thought it was a friendly, but then I checked the color code was red.
My record win is 16-0, both friendly and official. Apparently Buffs Mad won by 21:0 once, though he has no screenshot of it: http://forum.topeleven.com/top-eleve...tml#post271448
