Aaron Ramsey is hoping Arsenal's 3-0 home victory over West Ham can help the team believe they can turn around the Champions League deficit in Monaco in midweek.
Goals from Olivier Giroud, Ramsey and substitute Mathieu Flamini saw the Gunners claim an eighth win in nine games at the Emirates.
And the Wales midfielder is hoping the past two victories, including the FA Cup quarter-final victory over Manchester United, can help inspire Arsene Wenger's side to overcome a 3-1 last-16 deficit in Monaco on Tuesday night.
"We will go there and try to score three or more goals and hopefully not concede any, that is our target and is how we will approach it," the Welshman said.
"We had a sloppy first leg and we have made it quite difficult for ourselves, but it is not over yet.
"We are more than capable of scoring three goals. We scored three on Saturday and we believe in ourselves.
"So we will go into the game believing we can achieve that."
Germany World Cup-winner Mesut Ozil is also hopeful of overturning Monaco's advantage.
"When you believe in yourselves, a positive energy grows that you can achieve your aims. In football, things that may look unlikely can happen. I know that if we believe in ourselves and utilise our potential, we can still go through," Ozil told Arsenal Player.
"We need to score three goals and Monaco are a team that play defensively, but we have to take initiative and score the first goal as quickly as possible to boost our confidence.
"It is going to be difficult to score three times because they have defended well in the tournament so far, but if you look at our past matches and the way we played against Manchester United (in the FA Cup quarter-final) last week, I think there's a chance we can still progress.
"When you look at the Manchester United game, we controlled it and deserved to win the game, that just shows that if we convert what the manager encourages us to do into the games, we can achieve a lot."
