We bring you all the action from the matchday five matches including the games in Naples and Manchester where wins for the two Manchester sides will put them into the next round of the Champions League
It's no wonder Roberto Mancini looks a bit tense ahead of the tie as tonight's match is a bit of a do or die affair. Both sides need a win: if Napoli get one that means City will have to beat Bayern, which would be a big ask. Victory for City would see them qualify but that could be a tall order as Napoli haven't lost to a foreign team at the San Paolo stadium for 17 yearsPhotograph: Alberto Pizzoli/AFP/Getty ImagesThe first quarter of an hour is quite an even affair with both sides pushing forward and firing in a few shots. Then Napoli get their noses in front after 17 minutes, courtesy of some shoddy City defending. A Napoli corner is flung in towards the near post, where Edinson Cavani has stolen a march on Yaya Touré. He flicks a header goalwards and the ball hits first Aleksandar Kolarov and then Joe Hart on its way into the net. Not the sort of defending you'd expect from a team sitting on top of the Premier LeaguePhotograph: ReutersCavani goes mad, as do the Napoli fansPhotograph: ReutersJust after the half-hour mark it's Napoli's turn for some dodgy defending. Rather than being hoofed clear, the ball is played straight to David Silva, who shoots ... and the rebound falls to Mario Balotelli, who has an easy job of stabbing the ball into the empty net from four yards out. His celebration is in direct contrast to Cavani's, though he does extend his arms outward at one pointPhotograph: Giampiero Sposito/ReutersSilva and Napoli's Christian Maggio attempt to get the ball under controlPhotograph: Tony Gentile/ReutersFour minutes into the second half Napoli retake the lead courtesy of a smashing goal by Cavani. There's a neat and quick interchange of passes on the left before Andrea Dossena picks out Cavani around 15 yards out. He strikes the ball precisely and his first-time shot zips past Hart into the netPhotograph: Giampiero Sposito/ReutersIt must be cold over in Naples because the Napoli fans have lit some fires and all seem to be waving those silver insulating sheets you normally see around the shoulders of athletes after they've finished a marathon Photograph: Paolo Bruno/Getty ImagesEdin Dzeko fires a shot past Napoli defenders Salvatore Aronica, left, and Paolo Cannavaro, but unfortunately for Mancini's men it didn't trouble Morgan De Sanctis in the Napoli goalPhotograph: Salvatore Laporta/APDzeko gets to the ball before the Napoli defence but can't direct his header goalwards Photograph: Roberto Salomone/AFP/Getty ImagesNapoli's Ezequiel Lavezzi strides forward Photograph: Roberto Salomone/AFP/Getty ImagesThe final whistle goes and the Premier League leaders are looking down the barrel at Champions League elimination. They will need to overcome the unbeaten group leaders Bayern Munich at the Etihad in two weeks' time, but even then that will not be enough if Napoli win at VillarrealPhotograph: John Sibley/Action ImagesBack in Manchester, Benfica are the visitors, and the omens are good for a United victory. United have triumphed in six of the eight meetings between these two sides, the most famous victory being the 1968 European Cup final at Wembley. Benfica have yet to beat United at Old Trafford in their three visits but they're not the only team with such a record – United have only tasted defeat once in the 34 Champions League matches they've played at Old Trafford since 2005Photograph: Paul Ellis/AFP/Getty ImagesBenfica take a shock lead in the third minute after some nifty passing in the centre of the park creates space for Nicolas Gaitan on the right. He hits an effort across the face of the United goal where Phil Jones is waiting ... but the defender inexplicably sticks out a leg and slams the ball into his own net. It's the first time the youngster has got on the scoresheet during a United game – shame it's for the opposition Photograph: Paul Ellis/AFP/Getty ImagesIn an attempt to get United back in the game Nani goes on a jinking run in the Benfica half ...Photograph: Phil Noble/Reuters... until his progress is stopped courtesy of a scything challenge from Benfica's Ezequiel GarayPhotograph: Andrew Yates/AFP/Getty ImagesOn the half-hour mark United are level. Nani is out on the left and receives the ball from a United free-kick; he runs at Maxi Pereira and then whips in a cross towards the penalty spot where Dimitar Berbatov rises to place his header inside the left-hand post. Benfica do have grounds to grizzle about the equaliser though, as Berbatov was half a yard offside when the cross was put inPhotograph: John Peters/Man Utd via Getty ImagesNicolas Gaitan shields the ball from NaniPhotograph: Alex Livesey/Getty ImagesThere's relief at Old Trafford in the 69th minute when United take the lead. Patrice Evra puts a deep cross into the middle as the Benfica defence push out, but they're too slow and the ball is knocked down to Darren Fletcher, who clips it round Artur and then prods it into the empty netPhotograph: Alex Livesey/Getty ImagesThat relief turns to despair just one minute later when Benfica equalise, and again their goal can be put down to sloppy defending. United can't deal with Benfica's attack down the left and when the cross comes in it knocks Rio Ferdinand off his feet; the ball falls to Pablo Aimar, who taps it inPhotograph: Martin Rickett/PAAt the death, Berbatov finds himself alone in the area and on the end of a Fabio da Silva cross...Photograph: Robin Parker/EPA... but alas he sweeps his volley it over the bar. He really should have done better, and he knows itPhotograph: Phil Noble/ReutersThe United players trudge off after the final whistle. They're still second in the group but qualification to the last 16 is dependent on their last game in Basel, where they will need to avoid defeat in order to go throughPhotograph: Alex Livesey/Getty ImagesBasel's Marco Streller attempts to go past Otelul Galati's Adrian Salageanu during the Swiss side's 3-2 win in Bucharest, in which the Basel captain got their third goal.
