Napoli goalkeeper Alex Meret pulled out in the warm-up with a wrist injury, so Pierluigi Gollini started against his parent club Atalanta.
You can follow all the action as it happens on the LIVEBLOG.
Meret had originally been named in the starting XI, but just a few minutes before kick-off, it was announced that he would sit on the bench and be replaced by Gollini.
Initial information from Sky Sport Italia, DAZN and the club website point to it being a pain in his right wrist that had already been troubling him and intensified during the warm-up.
It is believed to be a precautionary measure, so Meret’s presence in the Champions League Round of 16 against Eintracht Frankfurt on Wednesday should not be in doubt.
Gollini therefore makes his Napoli debut, having joined in January on loan from Atalanta with an option to buy for €8m.
Before that, he had been on loan with Fiorentina, but rarely played.
