David Silva believes Manchester City have nothing to lose as they head into Wednesday's crunch Champions League game at Barcelona.
City travel to the Nou Camp needing to overturn a 2-1 deficit to reach the quarter-finals but Spain international Silva is taking succour from recent history.
The 29-year-old said: "Everybody wrote Schalke off before they played Real Madrid but they won 4-3 and could have scored again which would have put them through - nobody predicted that.
"Not many thought PSG could beat Chelsea, especially with only 10 men for so long, so I know that everything can happen, not only in the Champions League but in every game.
"Everyone is expecting Barca to go through but hopefully we can give a strong performance and we don't have any kind of pressure on us because we are behind and playing away."
City - beaten by Barcelona at the same stage last season - needed victories over Bayern Munich and Roma to progress from their group, successes which give Silva more cause for optimism.
He said: "We need this kind of mentality we showed in those games.
"The most important thing is not to concede a goal because obviously things then become more difficult. We played well in the second leg against Barca last season and played with freedom so we will see."
