Did not have to make a save in the first half, but was called into action midway through the second when he was at full stretch to keep out Bryan Ruiz's free kick.
Having failed to impress in the opening two games of the season, the former Lille right-back put in another below-par performance. His afternoon was summed up with a shot that flew miles off target at the end of the first half.
The Argentine showed his aerial prowess when he nearly put the home side in front with a header in the fifth minute and he was comfortable in defence throughout.
Looked slightly nervy at left-back up against the effortlessly stylish Bryan Ruiz, and looked far more confident when he was able to push forward and support his side in attack.
The young centre-back looked assured alongside Coloccini and showed good awareness on a couple of occasions to put in some timely tackles inside his own box.
Put the afterburners on twice in the early stages of the game to race away from Brede Hangeland, only to turn and see no Newcastle players arriving to support him. Fell into Hatem Ben Arfa's shadow after the break.
The Frenchman whipped some decent set pieces and crosses from open play into the Fulham box, including to set Fabricio Coloccini up early on.
H. Ben Arfa
The scheming attacker was Newcastle's brightest player throughout and he sealed all three points for his side with a divine finish past Robbie Stockdale after sashaying past John Arne Riise on the right.
Provided a sturdy platform in midfield for the more creative talents around him to try and find a breakthrough in the second half. Was replaced by Yohan Cabaye midway through the second half.
His main contribution in the first half was to block his own team-mate Coloccini's goal-bound effort early on. However, he linked well with Hatem Ben Arfa after the break as Newcastle went in search of, and eventually got, a winner.
The 31-year-old revived an old training ground rivalry with former Magpie, Aaron Hughes, but failed to come out on top in that battle, as he and Cisse were often left isolated in attacking areas.
Made a decent stop from Papiss Cisse in the 32nd minute after the striker brushed off the challenge of Brede Hangeland, and pulled off a couple more saves after half-time before being beaten by Hatem Ben Arfa's brilliant finish.
The former Liverpool defender had an incredibly tough time up against Hatem Ben Arfa, particularly when the diminutive Frenchman began to shine in the second half.
Played well at the back for the away side alongside Brede Hangeland, and will be disappointed to have been on the losing side on his return to St James' Park.
Dispossessed Ben Arfa superbly in the 17th minute, just as the Frenchman looked to ghost into the Fulham penalty area and looked confident for his side until he was forced off through injury in the 73rd minute.
Made two important clearances in the first half and continued to marshall the visiting side's defence well after the break.
Proved a nuisance for Newcastle's defence as he cut in from the left and took up dangerous positions inside the Magpies' penalty area.
The experienced midfielder performed well against his former employers, winning possession neatly on a number of occasions and starting attacks for his side.
Started the game well with some crunching challenges on Newcastle's chief creator Hatem Ben Arfa, and he worked effectively in midfield next to Scott Parker.
The flamboyant attacker was shifted out to the right as Martin Jol partnered Darren Bent with Dimitar Berbatov upfront and this limited his impact on the game. Forced a decent save from Tim Krul from a free kick in the second half.
The languid Bulgarian looked slightly out of sorts this afternoon as the game appeared to pass him by. Although he failed to test Tim Krul over the course of the game he did help out defensively, rather uncharacteristically.
The former Sunderland striker would have loved to have scored on his return to the North East but he had few chances to leave his mark on the game before being subbed off late on.
Was given a mixed greeting by the home fans after withdrawing himself from the squad for their game against Arsenal 12 days ago. His first involvement was to gift Fulham a free kick.
Introduced late on as Sylvain Marveaux made way but had little impact on the game in his first appearance for the club.
Had a good chance to put his team in front shortly after replacing Shola Ameobi but he headed agonisingly wide.
