Team news
Napoli are badly hit at the back, without Buongiorno and Spinazzola, with Rrahmani a doubt. Lobotka and Neres are also out. Porto reported no absentees.
Our prediction and why
We take Over 2.5 goals. Napoli scored three or more in three of their last five and Porto scored in all five, which fits our rule. Seven of the two teams' last ten games had three or more goals. With no recent meetings to go on, we rate it lower than our other picks.
