Well that kinda cheapens your argument a bit, mate, in fairness.
Leeds had pretty much none of the game and the only reason Man City didn't score a hatful was that their forward line were having a rancid off-day. They carved them open time and again and just couldn't finish. Leeds didn't deserve the win or play well.
Also, I don't think it's helpful to use outliers like that match to try and prove a point - it's like when people say that 'well Messi played at 18, so why can't our kids do that?' - it just doesn't work for me.
