City needed a 74th-minute free-kick from left-back Aleksandar Kolarov to secure a share of the spoils in their much-anticipated Group A opener at the Etihad Stadium in response to Edinson Cavani’s effort from a classic breakaway move in the 69th minute.
City did squander numerous chances, hitting the woodwork through Yaya Toure and Sergio Aguero, but Napoli also hit the bar and their speed and resilience highlighted the step up in intensity Mancini’s men face.
“I think we can do better in Munich because it is the second game. This game was important for us and I think we were nervous, all the club was so nervous,” Mancini said.
“I think we played very well in the first half but in the first 15 minutes of the second half we conceded a lot of space to Naples.
“They were really dangerous and they scored a goal.
“A team like us can’t concede goals like this. When we lost that goal we didn’t have any midfielders in front of the defenders. For 10 minutes we left a lot of space for Napoli players. After that I was happy with our performance – as in the first half – when we played very well.”
