I think you miss the point a little bit. Docking Man City, let's say 3 points, and rearranging the table to put Liverpool top is more cruel than anything since not only did you not get to enjoy a title win at the time, you also had to endure a summer of "what if" and "if only"
I guess you'd get to say it's now 19 league titles instead of 18 but you've lost the visceral moment of actually doing it and it will always be marked with an asterisk.
Gerrard slipping, after saying this does not slip, will never not be funny, regardless of what happens.
Think of it this way... when John Terry slipped in the 2010 CL final and missed the penalty, it hurt for a long time. But I can see how Man United fans will never not love it - even if it's revealed that all their players were on PEDs or something. It also made the 2012 CL win sweeter.
Truth be told, I'm hoping Liverpool can go this season unbeaten and shut the Arsenal fans up about being invincible
