The match has not been played. This is not a tip: the model turns the chances both sides create and concede into probabilities, and it is wrong regularly.
Roma are favourites: 59% to win against 22%. Attack against defence: Roma should create more, 2.27 expected goals a match against 1.45. Napoli are 1.8 points short of what their play deserved — more dangerous than the table suggests.
Probabilities come from a Poisson model over both sides' xG with a home advantage applied. We know nothing about injuries, suspensions or rotation, and we do not give betting tips.
