Man City have inflicted a 2-1 defeat on PSG in the first leg, as they scored twice after the break to take lead after Marquinhos had put the Ligue One giants ahead in the game.
It's advantage Man City at the moment, but Neymar thinks every Parisian should believe they can turn it around in the second-leg, which will take place at the Etihad Stadium next week. The Brazilian has also promised to give his best against the Premier League side, and do anything to win the tie.
"We had a very tough first leg against Manchester City but we have to believe it no matter what the stats say or our percentage chance of winning.
"I think every Parisian should believe in us! I’m in the front line, and I’ll be the first warrior who goes into battle for the team.
"I will give the best of myself and I will do anything to bring this back no matter what, even if I have to die on the pitch."
