Manchester City manager Roberto Mancini will not give up hope of his side qualifying for the knockout stages of the UEFA Champions League.
A defeat at Napoli in their penultimate Group A game means the current Premier League leaders no longer have progress in their own hands.
City, who were beaten by two goals from Edinson Cavani either side of Mario Balotelli's equaliser, now have to hope the Serie A club slip against pointless Villarreal on Matchday Six.
To add to the tough situation, Champions League debutants City would also need to defeat Bayern Munich at Etihad Stadium in two weeks' time.
But Mancini will not write off his side's chances, as he told Sky Sports HD2: "We have another game and Villarreal can beat Napoli.
"It is the first time we have played Champions League but I don't think Villarreal will lose another game, they can win or draw - why not?
"Everything is not finished - never say never."
Reflecting on the setback against Napoli, Mancini added: "We didn't deserve to lose this game, we should think we can score three or four goals every game. We wanted this because that is our mentality.
"After our equaliser, we had two more chances to go 2-1 up, it is strange that we conceded this goal after 10 minutes.
"We had other chances to score, their goalkeeper was fantastic and saved three or four chances. But if you lose, probably you made mistakes.
"We conceded two stupid goals, we know Cavani goes on the first post. Cavani is a good player, a good striker, he scores goals and works for the team."
