Indeed - However I dont think it is that simple:
Rules are precident as much as, if more than, writing. If a law is continuously applied in a certain way, that law, in practice, becomes pretty much accepted.
Take the 'no pushing at a corner' rule.
Lets say your team conceded a penalty because somebody was pushing and shoving at a corner, and everybody got the rule book out to say how amazing a decision it was? My argument is, the fact that it happens regularly and is never punished, renders the rule effectively meaningless.
I am simply saying that it is wrong that a rule which is almost never applied, is suddenly applied in the most important game of the season. I have said, and will continue to say, it had little or no bearing on the result as you were clearly the better team. I just get frustrated by the blatant inconsistency.

Sorry to repeat myself but - in the liverpool chelsea game. Chelsea players both go off at the same time. Ref allows them back on immediately. Carbon copy incident in the liverpool cardiff game, our players are off the pitch while liverpool score a goal from a corner...
