There are 90 minutes left of the season and four teams can still finish third and qualify for the Champions League.
Udinese are in pole position for third. They’ll achieve that target with a win or even a draw at Catania. A loss could still be enough if Napoli don’t win and Lazio-Inter ends in a draw.
Lazio, currently in fourth and two points adrift, will finish third if they beat Inter and Udinese – who have a better head-to-head record against them – lose.
Napoli, fifth with three points to make up, will celebrate if they beat Siena, Udinese lose and Lazio don’t win.
Inter, meanwhile, can only celebrate if they beat Lazio, Udinese lose and Napoli fail to win.
Udinese are in control of their own destiny as a point will be enough, while the other three need wins and a favour or two from elsewhere.
