Sergio Aguero became Manchester City's all-time leading goalscorer in a 4-2 win at Napoli that saw them qualify for the Champions League knockout phase with two games to spare
Aguero underscored his name in the City history books with the winner on 69 minutes - his 178th goal for the club, one more than Eric Brook
Lorenzo Insigne had given Napoli a deserved 21st-minute lead only for Nicolas Otamendi (34) and John Stones (48) to turn the game around
Jorginho drew Napoli level from the penalty spot on 62 minutes but further goals from Aguero and Raheem Sterling secured City's passage to the last 16
City only needed a point to reach the last-16 but a lacklustre start gave a Napoli side, keen to keep their Champions league dream alive, hope early on
Marek Hamsik, looking to equal Diego Maradona's goal tally for Napoli, drew Ederson into action from distance on six minutes, while City struggled to match the intensity set by the hosts
Dries Mertens had a goal disallowed for offside on 19 minutes but Napoli were not to be denied much longer as his one-two released Insigne, who fired high past the City goalkeeper two minutes later
But, after the impressive Faouzi Ghoulam was forced off injured, City awoke from their slumber
 Aguero fired wide on 32 minutes but the visitors were soon level as Otamendi headed his first Champions League goal beyond Pepe Reina
Stones rattled the crossbar before half-time but atoned within three minutes of the restart as goal-line technology ruled his header had crossed the line, but City's hard work evaporated when Jorginho converted a penalty after Leroy Sane's foul on Raul Albiol
Despite having the point they needed to qualify, City pushed on and took the lead for the second time as Aguero sealed his place in history at the end of a flowing counter before Sterling added the finishing touch in stoppage-time
City's victory and their place in the last 16 was effectively secured by Aguero's goal, and it is a moment that will be remembered for much more as the Argentinian claimed his place in club history
 Brook's record of 177 goals had stood since 1939, but, as he has done throughout his City career, Aguero showed great composure to find the net
"Unfortunately by attempting to win we got a little carried away and it cost us
 But I liked the squad's approach
 I prefer trying to win even if that means having to take risks
 We were facing one of the best teams in Europe and we were aware of the difficulties
""We cannot expect to control 90 minutes, we are going to suffer
 The point is how we are going to overcome and react to that situation
 We did it twice, after 1-0 and after 2-2
 That's why I'm so pleased
"Manchester City look to maintain their unbeaten start to the season when they host Arsenal on , live on
