Roberto Mancini believes that Manchester City face a tough task when they take on Napoli in their next Champions League match.

City, who comfortably beat Villarreal 3-0 on Wednesday night, next travel to Naples for their crucial Group A clash.

Both sides can still qualify for the knockout stages of the competition ahead of the match at the Stadio San Paolo on Tuesday, November 22.

"I think it will be an incredible atmosphere," said Mancini.

"At night, playing under the lights, Napoli almost always win at their own ground. They beat every team they play. But we have a very good chance to qualify now.

"We know that everything will depend on what happens in Naples and that if we win we will go through and, after that, anything can happen."

Napoli lost 3-2 to Bayern Munich in their Champions League match on Wednesday night.
