Callejon makes a poor challenge on Kolasinac and gets a yellow card for his troubles. The free-kick is in a dangerous position for the Gunners.
88'
A couple of silly fouls slow the pace of the game down. Both sides seem to have accepted the result.
86'
Chiriches concedes a corner, which Arsenal take their time over, but it eventually comes to nothing. Not long left to go now.
84'
MISS! Fabian's corner finds the head of Koulibaly, but he can only direct it wide of the target. Things just haven't gone Napoli's way in front of goal tonight.
78'
Zielinski has yet another shot that fails to hit the target. He's another whose shooting has been very poor tonight.
76'
Torreira has gone down and it looks like he could have suffered a reoccurrence of the groin injury he suffered against Watford. Emery has used all his substitutions, however, so the Uruguayan will have to play on or Arsenal will be reduced to 10 men.
74'
P. Čech gets yellow.
Cech takes the ball across his six-yard box for a goal-kick and is shown a yellow card for time-wasting. He's not happy at all about the decision.
71'
Mário Rui enters the game and replaces F. Ghoulam.
Ghoulam goes off for Rui in a like-for-like change at left-back.
69'
Koulibaly is bundled over by Koscielny in the area during a corner and tempers flare, particularly from the Napoli defender. Sokratis plays peacemaker and things cool down eventually, but things were threatening to spill over at one point.
Minute
Description
68'
A. Iwobi enters the game and replaces A. Lacazette.
Lacazette trudges off for Iwobi as Emery rests another of his key men. He and Mkhitaryan will flank Aubameyang in attack.
67'
MISS! Callejon swipes at a shot and it flies high and wide. His finishing, in particular, has been very wayward tonight.
66'
BLOCK! Milik takes a strike in the middle of the box but it's amidst a sea of red and white shirts and it's blocked away.
65'
Elneny charges down Meret and it's played over the top of him. Napoli surge forward and try to work a chance, but Koscielny sees the ball behind for a corner.
63'
MISS! Mertens' corner finds the head of Chiriches, but he can't quite steer it on target and it bounces wide.
61'
A. Younes enters the game and replaces L. Insigne.
Mohamed Elneny enters the game and replaces G. Xhaka.
Xhaka makes way in midfield for Elneny as Emery freshens things up.
Napoli replace their captain and talisman Insigne with Younes.
58'
SAVE! Chiriches concedes a corner and it's worked to Aubameyang. He takes on the shot from a tight angle and it's saved comfortably by Meret.
54'
Lacazette bundles Allan over and concedes a free-kick. The Gunners are happy to let the game peter out.
50'
Napoli are huffing and puffing but they just can't create anything of note. Arsenal reasonably comfortable so far.
47'
MISS! Fabian blazes high and well wide from outside the box. There's more than a hint of desperation in that effort.
46'
D. Mertens enters the game and replaces N. Maksimović.
Mertens comes on for Maksimovic as Ancelotti replaces a defender with a forward. Napoli need goals.
We're back underway for the second half!
45' +4
HALF-TIME: NAPOLI 0-1 ARSENAL
45' +3
BLOCK! Zielinski tries his luck again but his effort is also blocked away. Allan tries to retrieve it but his low cross goes out for a goal-kick
45' +2
BLOCK! Insigne has a pop from the left outside the box but Mkhitaryan gets in the way and deflects it behind for a corner.
45'
MISS! Zielinski has a very ambitious attempt from over 35 yards out and predictably misses the target. Awful decision.
43'
L. Insigne gets yellow.
Insigne is booked as his frustration bubbles over. Napoli have a real mountain to climb.
40'
Koulibaly plays a lovely ball forward that Insigne plucks out of the air expertly, but the Italian had gone a fraction too early.
38'
Kolasinac barrels down the left and pushes past Callejon, who goes down and a foul is awarded. A little over-zealous from the left-back.
36'
A. Lacazette has scored a goal for Arsenal!
GOAL!! ARSENAL OPEN THE SCORING! Lacazette lines up a free-kick in a central position and whips it to the goalkeeper's side sweetly. Meret goes the wrong way and it nestles in the corner! Arsenal are 1-0 up on the night and 3-0 up on aggregate! Napoli need four without reply now.
34'
H. Mkhitaryan enters the game and replaces A. Ramsey.
The midfielder limps off and the change is made. Mkhitaryan replaces him and will operate behind the two strikers, as Ramsey was doing. Concerning for the Gunners.
27'
Allan clatters into Xhaka and leaves him on the turf. He's okay but trudges to the sideline for some treatment before returning to the field.
25'
Ramsey tries to force home inside the box but it's too crowded and he can't squeeze a shot on goal. He's then bundled over on the left but doesn't get the decision.
22'
Fabian tries to play in Ghoulam down the left in a wonderful crossing position, but the left-back is a whisker offside.
21'
There's a coming-together between Insigne and Kolasinac and neither player is happy with the other afterwards. Nothing comes of it though and play carries on.
19'
MISS! Fabian receives the ball from Zielinski and has a pop from outside the box on his left, but he drags it harmlessly wide.
18'
Aubameyang is sent scampering down the right, but he holds the ball a little too long before trying to find Lacazette in the middle and his cross is blocked behind for a corner, which comes to nothing.
16'
Arsenal break quickly and efficiently, but Aubameyang is closed down on the left and the ball is forced out for a corner, which doesn't find a red and white shirt.
15'
Insigne takes the ball down well on the left and tries to spin past Koscielny, but the defender gets a toe in and snuffs out the attack well.
13'
Chiriches lumps forward for Milik, but the Polish striker is caught offside. He'd have been one-on-one with Cech in acres of space if the flag hadn't gone up.
12'
Kolasinac races onto a clever Aubameyang back-heel on the left and heads for the byline. His final touch is a little heavy, however, and in anticipating a challenge from a defender, inadvertently lets the ball run out of play. What a waste of a good crossing position.
10'
NO PENALTY! Ramsey is bundled over in the box and looks at the referee imploringly, but he isn't interested and waves the game on.
8'
The delivery forces Meret to punch to the edge of the box, where Ramsey attempts an ambitious volley, but his effort lacks conviction and hits Koscielny before going behind for a goal-kick.
7'
Arsenal win a free-kick on the right through Maitland-Niles. It's so near to the corner flag that it's essentially a corner kick. Xhaka stands over it.
5'
Xhaka pings the ball forward for Kolasinac, who crosses into Lacazette in the box. The Frenchman has his back to goal and lays it off for Ramsey, but there's no space and the midfielder ends up conceding a foul.
3'
Lacazette wins a free-kick in a dangerous area and it's floated towards Aubameyang at the back post. He meets it but there's a sea of light blue shirts in the way and it's comfortably blocked away.
1'
We're off in Naples!
Hello and welcome to our LIVE coverage of the Europa League quarter-final second leg fixture between Napoli and Arsenal at the San Paolo Stadium in Naples.
Napoli XI (4-4-2): Alex Meret; Nikola Maksimovic, Vlad Chiriches, Kalidou Koulibaly, Faouzi Ghoulam; Jose Callejon, Allan, Fabian Ruiz, Piotr Zielinski; Arkadiusz Milik, Lorenzo Insigne
Napoli substitutes: David Ospina, Kevin Malcuit, Mario Rui, Dries Mertens, Simone Verdi, Elseid Hysaj, Amin Younes
Arsenal XI (3-4-1-2): Petr Cech; Sokratis Papastathopoulos, Laurent Koscielny, Nacho Monreal; Ainsley Maitland-Niles, Lucas Torreira, Granit Xhaka, Sead Kolasinac; Aaron Ramsey; Alexandre Lacazette, Pierre-Emerick Aubameyang
Arsenal substitutes: Mesut Ozil, Alex Iwobi, Mohamed Elneny, Matteo Guendouzi, Bernd Leno, Shkodran Mustafi, Henrikh Mkhitaryan
Napoli are going to have to galvanise themselves and remain focused if they are to pull off a remarkable comeback in the second half. They've been caught offside far too many times - as was the case in the first leg - and been very wasteful with the few opportunities they've created.
Arsenal take on Crystal Palace at home in their next game as they continue their top-four battle in the Premier League, while Napoli have to dust themselves off and go again when they host Atalanta in Serie A.
That's all from us, we hope you enjoyed the game! Until next time, goodbye!
