Highest scoring game I can remember against human opposition was a 6-4 win. 15mins 5*. I was down 4-0 at half time, some tactical tinkers and I came back to score 6 in the second half. One of the best matches I've ever had on any PRO EVO. Such emotions...
I even spent the time to write a match review (as i do occasionaly) which you can read here \/. Well worth five minutes of your time. Even if I say so myself.

Highest scoring game against the computer was a 14-1 drubbing of Manchester City. League game, 5* 15mins.
EDIT= I've just been reading some old posts and found an 8-1 defeat. Very ashamed but it was a rarity. And it's never happened before or since. In fact against the same guy, I haven't conceded more than 2 in any one game (and that's good cos he's shit hot), I always score more though. He has beaten me very rarely since....
Remember the Liverpool Newcastle 4-3 games? That's what it's like whenever we play.... Respect to McNab.
