Milan, Napoli and Juventus go into the final weekend battling for a top four finish, but there are a series of possible combinations.
The Rossoneri and Partenopei both have 76 points, followed by the Old Lady on 75.
While Milan visit Atalanta, Napoli host Hellas Verona and Juve are in Bologna.
It could well go down to a head-to-head record, but there is also the possibility they could all finish together on 76 points, sparking a classifica avulsa (a mini-league of their results against each other).
In that case, Milan and Juve would go through to the Champions League, with Napoli in fifth place.
Milan 76 points
If Milan beat Atalanta, they will not only secure a Champions League spot, but also leapfrog La Dea to take second place.
Milan have a superior head-to-head record with Napoli and with Juventus.
Napoli 76 points
If Napoli beat Verona, they will guarantee a top four finish.
Napoli have an inferior head-to-head record and an identical head-to-head record with Juventus.
When the H2H is equal, it goes to overall goal difference and Napoli are a long way out in front of Juve (+45 to +36).
Juventus 75 points
Juventus must beat Bologna and hope that either Milan or Napoli fail to pick up three points.
There is an alternative, as they could draw with Bologna, as long as both Milan and Napoli lose.
In that case, they would all be on 76 points, setting off a classifica avulsa – a mini-league made of their results against each other.
This would see Milan, Juve and Napoli all on six points each, so calculating the goal difference in that mini-league, Milan and Juventus would have the upper hand, sending Napoli to fifth place.
That’s because Milan have a goal difference of +2, while both Juve and Napoli have a goal difference of -1.
The Bianconeri would get the advantage, as they scored five goals and Napoli only scored four in this mini-league.
