The Brazilian believes the Blues will have to give their best Champions league performance yet in order to beat the Catalans and turn around a 2-1 deficit.
And like David Silva, he says City will take heart from the performances of Schalke and PSG last week with the away sides producing stellar displays against Real Madrid and Chelsea.
“Our intention is to go to the Nou Camp and win - it’s the only option we have, but to do so we must play in a compact way that prevents giving Barca too much space.
We have to play the best game of our lives and make it to the next round
...Fernandinho...
“Last week, there were two teams that played with character away from home and our intentions are the same.
“Schalke and PSG played great football, and our team can probably be inspired by these two teams and their results - maybe it can help a little bit. But more important than that is to make sure we do our job, play our game, play against Barcelona on the same level and try to win.
“In the first leg it was clear that PSG were determined to win from the first minute, and it was the same again in the second game, but based on the circumstances of that game and with a player been sent off in the first half, playing away, not many people believed that they could manage to qualify but they ended up doing it.
“That revealed the strength of their team, the quality of their players and better than that, football won.
“The team that attacked more and aimed the win from the very first minute managed to qualify and I think everyone was happy with that so that’s what we have to do.”
