The former Liverpool goalkeeper made a number of solid saves, commanding his area well and denying Tiendalli's last header brilliantly.
The Algerian left-back was reasonably solid but his free-kick deliveries let him down.
The Brazilian looked shaky throughout, unable to deal with the physical presence of Bony and the technical ability of Pablo Hernandez.
Made a number of important interceptions and headers, clearing an Emnes effort off the line in the early stages, as he held the Napoli defence together.
The Swiss midfielder battled well, providing some bite in the Napoli midfield. He didn't carve out too many chances, but helped to keep the hosts' in the game.
Couldn't deal with Hernandez driving inside from the left flank, failing to press forward or nullify his man.
Netted in stoppage time to wrap up the victory, turning home a cross at the back post. His effort was excellent, and he wasn't afraid to try his luck from range.
Took his goal fantastically, lofting the ball over Vorm to give Napoli the lead. His tendency to shoot and his dribbling ability always kept the away side guessing.
The veteran Macedonian midfielder wasn't up for the physical rigours of the game, but linked midfield to attack well in the first half, releasing Higuain on two occasions.
Was kept reasonably quiet by Davies and often tackled or fouled before he got into full flight.
Took his goal brilliantly, capitalising on a defensive error to smash the ball home. Had plenty of opportunities, only managing to convert one, but kept Swansea nervous all night.
The Dutchman made a few smart stops, but wasn't tested as often as his opposite number. Helpless to stop Insigne, Higuain or Inler putting the game beyond his side.
Made important clearances and helped to organise his side and almost complete a famous upset.
Should have tracked Insigne's run for the opening goal, but otherwise kept tabs on his man brilliantly. Was unfortunate to see his late header tipped over the bar.
Put his body on the line for the cause, taking an Inler strike to the face, and covered well at times to clear up behind Williams.
Unfortunate to deflect Chico's attempted clearance into the path of Higuain for the hosts' second goal, and struggled against Mertens. His effort and commitment was good though.

Took his goal excellently, driving through on goal and firing beyond Reina, and always looked to overload and push forward.
Caused plenty of problems when cutting in from the left, playing in between the lines excellently and finding pockets of space. Unfortunate not to test Reina more often.
An impressive technical performance, picking up the pieces and keeping things moving in midfield for the away side.
Offered plenty of width and delivered two good crosses from the left hand side. Neat and tidy throughout.
Unplayable all evening, holding the ball up brilliantly and causing plenty of problems for Henrique and Albiol. Just couldn't find the back of the net.
Offered width in the first half, holding onto the ball well and beating Ghoulam on several occasions.
