Roberto Mancini has said that Manchester City are braced for a "difficult" Champions League clash with Napoli tonight.

A victory for City would seal their place in the last 16 of the tournament, while Napoli will be fighting to stay in the competition.

"The team is in good form," Mancini said. "Every game is difficult but we are playing every three days, it is hard. Tomorrow will be so different from the other games because it is the last chance for Napoli.

"It will be a very difficult game for us. For us it's the first time so I don't know if it will be possible but for this reason we want to try to get into the second stage and if we want to do this we should win.

"After that anything can happen because we are a good team, we can improve a lot, but before we should think only regarding the game."

City players have already received a hostile welcome in Naples, and travelling fans have been warned to be vigilant.
