Click here for the live goals as they go in
Napoli: De Sanctis, Campagnaro,
Cannavaro, Aronica, Maggio, Inler, Gargano, Zuniga, Hamsik, Lavezzi,
Cavani.
Subs: Rosati, Grava, Dossena, Dzemaili, Fernandez, Pandev,
Britos.
Chelsea: Cech, Ivanovic, Cahill,
Luiz, Bosingwa (Cole 12), Ramires, Meireles, Malouda, Sturridge, Drogba, Mata.
Subs: Turnbull, Essien, Lampard, Torres, Mikel, Kalou.
Referee: Carlos Velasco Carballo (Spain)
23min: Chelsea are trying to regain some composure here by keeping the ball and it's starting to frustrate the home fans who are booing heavily.
20min: Another fine Cech save. Lavezzi plays an inch perfect pass behind Luiz, and the centre-back is beaten for pace by Christian Maggio.
The full-back, although at an acute angle, shoots from a promising position but the Czech stopper superbly palms across his goal for a corner.
17min: Nearly a chance out of nothing for Chelsea. Morgan De Sanctis comes for a long ball but seems to shy away from claiming it once he knows Florent Malouda will challenge him for it.
The winger comes out on top but can't find a direct route to goal as the attack fizzles out once his cross from the left is cleared.
A big 'man up' shout to Campagnaro though who after challenging the Frenchman went down like a sack of spuds claiming he had been hit in the face. That clash with Drogba seems to have affected his nerve senses.
15min: It's not one-way traffic but Cahill and David Luiz are being stretched at the back early on for Chelsea. Villas-Boas is already on the edge of his technical area trying his best to compose his team who look a little nervous.
12min: And it gets worse for Chelsea. Bosingwa has pulled up with hamstring problems so Ashley Cole is on to replace him.
11min: What a let-off for Chelsea. Edinson Cavani beats the offside trap by racing past a static Gary Cahill, but his low near post shot is superbly stopped by Cech with his foot. You would back the Uruguayan to score those.
8min: A slight delay in play after a clash of heads between Didier Drogba and Hugo Campagnaro results in both needing treatment.
The Ivorian looks okay but Campagnaro has had his head all bandaged up – he looks much like Paul Ince for England when the Three Lions visited Rome in 1997.
6min: A lovely long ball from Paolo Cannavaro splits Branislav Ivanovic and Gary Cahill, but Petr Cech is quick out of his goal to beat Ezequiel Lavezzi to the ball.
3min: Chelsea have opened cautiously, defending quite deep early on – probably a wise tactic if it's at least to quieten down this partisan crowd.
Kick-off: The hosts get us underway.
19.44: From OptaJoe:
13 – In the 13 Champions League games Terry has missed for Chelsea they have never lost (W8 D5). Missing.
19.41: Out come the players, incredible atmosphere, inside the ground.

So when's kick-off Napoli fans started entering the San Paolo hours before the start of the game
19.38: Still a very wet pitch in Italy, but this place has been filling up with fans since half-three – now that's dedication.
19.35: It was about this time six days ago that we were preparing for Milan v Arsenal where the Gunners were thrashed 4-0.
Villas-Boas is a little bit more upbeat on Chelsea's chances, saying 'nothing will be decided tonight.'
19.32: Plenty of talk has surrounded the atmosphere at the San Paolo.
But if you want to know just how big it is, then check out ex-Chelsea and Napoli star Gianfranco Zola's take on the 'lion's den.'
19.29: Ashley Cole joins John Terry in failing to make Chelsea's Champions League clash at Napoli tonight.
Blues captain Terry was today ruled out for several weeks after aggravating a knee problem, while Cole (calf) is not risked, meaning Jose Bosingwa starts at left-back.
Manager Andre Villas-Boas makes a huge decision by drafting in Florent Malouda instead of Frank Lampard, but he does axe Fernando Torres for Didier Drogba, as expected.
Napoli recall fit-again goalkeeper Morgan De Sanctis and make three further changes.

Testing conditions: Chelsea players train at the rain soaked San Paolo on the eve of their clash at Napoli
19.26: Full team news from the San Paolo:
Napoli v Chelsea
Napoli: De Sanctis, Campagnaro, Cannavaro, Aronica, Maggio, Inler, Gargano, Zuniga, Hamsik, Lavezzi, Cavani. Subs: Rosati, Grava, Dossena, Dzemaili, Fernandez, Pandev, Britos.
Chelsea: Cech, Ivanovic, Cahill, Luiz, Bosingwa, Ramires, Meireles, Malouda, Sturridge, Drogba, Mata. Subs: Turnbull, Cole, Essien, Lampard, Torres, Mikel, Kalou.
Referee: Carlos Velasco Carballo (Spain)
19.23: And it's because of Napoli's impressive 2-1 win against Manchester City that many fancy them to win tonight. I must be in that minority camp again that thinks Chelsea are going to get a result.
Plenty of talk about Villas-Boas' team section though – Jamie Redknapp has called it 'managerial suicide'. I admire the manager for sticking with a side he thinks is best equipped to get a result – despite the supposed internal politics.
19.20: Sportsmail's Ian Ladyman:
Main memory from Napoli with #mcfc is atmosphere and Lavezzi cutting in from left on his right foot. back three aren't the quickest tho. #cfc
19.17: From OptaJoe:
54 – Chelsea fired in the most shots on target in the group stages (54), however Napoli had the best conversion rate 22 per cent. Clinical.

Surprise selection: Jose Bosingwa replaced Ashley Cole at left-back for Chelsea
19.14: One result already in the last 16 tonight. Pontus Werbloom scored in the third minute of added time to steal a 1-1 draw at home for CSKA Moscow against Real Madrid, who opened the scoring after half-an-hour through some chap called Cristiano Ronaldo.
19.11: Napoli starting XI:
De Sanctis, Aronica, Campagnaro, Cannavaro, Maggio, Hamsik, Zuniga, Gargano, Inler, Cavani, Lavezzi.
19.08: I have a feeling Villas-Boas may be a little more confident going into this evening. The reason why Just check out this advice from ex-Chelsea boss Avram Grant:
'My advice to Andre is to try and do his job and win games. What will happen will happen.'
The young Portuguese manager can't go wrong now…can he
19.05: Still surprised there is no John Terry Here is why.
19.03: Sportsmail's Matt Lawton at the San Paolo:
Chelsea team is Cech, Ivanovic, Luiz, Cahill, Bosingwa, Ramires, Meireles, Malouda, Mata, Drogba, Sturridge. Cole and Lampard on bench.
19.00: If you want to read more on the managerial situation at Chelsea then may I kindly point you in the direction of Sportsmail's Martin Samuel, who has written a cracking piece dedicated towards it. Read it here.
18.55: A big night for Andre Villas Boas. If I was him I would take cover somewhere and not appear for a few days if Chelsea lose.
The Blues boss is under pressure as it is considering the club's poor league showing and dodgy cup performances so could really do with some luck.
For the record, I still back him to do a decent job at Stamford Bridge given the time. But it does feel I am in a minority.
18.50: Sportsmail's Matt Lawton at the San Paolo:
'Just asking myself why I left my hat and gloves at the hotel.
'Deafening boos from Napoli fans as Chelsea keepers come out to warm up. Kitman got much the same treatment earlier.'
18.45: Has it really come to this The last 16 of the Champions League and it already looks like we only have one Premier League team to carry us through the knockout stages.
So all hopes pin on Andre Villas-Boas (for how much longer) and Chelsea as we focus on the second Premier League team to travel to Italy inside a week…maybe fans on these shores might have something to cheer this time. Team news coming up.

Been there, done that: Chelsea will look to Didier Drogba to carry them through a tough test at Napoli
