It is worth noting that now Inter and Lazio are tied in the head-to-head matches, as the goals scored away from home do not count in Serie A. This means that, should the two teams be tied in points at the end of the season, the tie-breaker would be the goal difference, which at the moment has Lazio ahead of us.
Unless more than two teams are tied in points, in which case all the points (and goals scored) among those teams (the third being juventus of course) should be counted.
We are at the moment behind in that scenario as well.
