#3 Serie A
Already qualified: Juventus, Napoli
In the reckoning: AS Roma, Lazio, Inter Milan
This has to be the closest season in Serie A in recent memory. Unlike the other leagues, this one hasn't produced a winner yet and is set to go right down to the wire.
Juventus and Napoli have been in a league of their own, and irrespective of who clinches the title, both have already secured a passage into the group stages of Champions League.
That leaves Roma, Lazio, and Inter fighting for the remaining two spots. UEFA's decision to let four representatives from each of the top 4 leagues means Serie A would have 4 teams in the Champions League for the first time, but one of these would still miss out.
Roma, currently on third with 73 points, need to win both their games to maintain their position ahead of Lazio, should the latter pick up maximum points from the remaining 2 games.
If that happens to be the case, Inter automatically drop into Europa League, as the final matchday would see the sides go head-to-head in Rome.
The Nerazzurris are fifth with 69 points, two adrift of Lazio, and need the latter to drop points in the penultimate matchday. Else, beat them in the final one, whilst picking up three points against Sassuolo in the other game.
Roma have their own fair share of challenges too, as they host Juventus before mounting a trip to Sassuolo for the final game. However, just a point from these games would be enough to go through.
If the fourth and fifth-placed sides end up on same points, then head-to-head results would be considered: A tie between Inter and Roma would see the former going ahead, while the winner of Lazio vs Inter will earn Champions League football if both end up on same points after matchday 38.
Now, here comes the tricky part - what if all three teams end up with 73 points each? Roma would need to lose both their games to bring about the situation, while Lazio needs to draw theirs.
A win and a draw for Inter would bring them level with the Rome outfits. Then, in this case, Lazio, who lament an inferior head-to-head record against both sides, would drop into Europa League.
