Rafa Benitez shakes things up with Dries Mertens, Rafael and Juan Camilo Zuniga starting in Napoli-Porto.
This is their second match in the Emirates Cup in London, as on Saturday the Partenopei drew 2-2 with Arsenal  and Porto lost 1-0 to Galatasaray after missing two penalties.
It kicks off at 14.00 UK time at the Emirates.
Benitez has revamped the line-up that started against Arsenal, as some players are moved around. Goran Pandev played as a centre-forward yesterday, but here starts in a deeper role behind Emanuele Calaiò – who will likely be replaced by Gonzalo Higuain for the second half.
Former Santos goalkeeper Rafael, ex-Liverpool full-back Andrea Dossena and new buys Mertens and Jose Maria Callejon all start.
Zuniga is one to watch, as he has still not signed a new contract and was greeted with jeers in a recent friendly amid reports of a move to Juventus.
Jackson Martinez is a transfer target for Napoli, but only starts from the Porto bench. Former Pescara midfielder Juan Fernando Quintero is in the starting XI.
Napoli: Rafael; Zuniga, Gamberini, Fernandez, Dossena; Dzemaili, Radosevic; Mertens, Pandev, Callejon; Calaiò
Porto: Helton; Otamendi, Fucile, Mangala, Alex Sandro, Fernando, Herrera, Varela, Josuè, Quintero, Ghilas
