If two teams in Serie A have the same points how are they sorted. Is it by goal difference or results between teams first. Is this the same for all the Italian leagues (ie Serie B C etc)?
Actually, I think this rule changed a few years back - now, teams are separated based on the results between them, and then goal difference.
From Wikipedia...
Before the 2005–06 season if two or more teams were tied in points for first place, for only one spot in a European tournament, or in the relegation zone, teams would play tie-breaking games after the season was over to determine which team would be champion, or be awarded a European tournament spot, or be saved or relegated. Since 2005-06, if two or more teams end the season with the same number of points, the ordering is determined by their head-to-head records. In case two or more teams have same total points and same head-to-head records, goal difference becomes the secondary deciding factor.
