Someone should make a "truthful" Serie A table.
Search for "classifica senza errori arbitrali", although they don't work very well as they are literal, i.e. they take off or add on a goal based on what is generally perceived to be a refereeing error, but don't bear in mind match conditions and how teams approach a game based on the score line.
There is no way of knowing how a game will pan out based on a red card, for example, and you cannot say that if you chalk off a goal for a team who had won 2-1 that the team would still not have gone and scored a second goal. That team played to the score at the time.
