Arsenal midfielder Mesut Ozil admits an early goal will be pivotal to his team's chances of overhauling a two-goal deficit against Monaco on Tuesday night.
The Gunners face the almost impossible task of overcoming last February's 3-1 defeat at the Emirates in the Champions League.
But the Germany international believes Arsenal have a chance to reach the Last 8 of the competition.
"It's very important to score early, but we will remain patient," Ozil told the club's official website.
"We want to fight and battle from the first minute until the last.
"This is a match that we are determined to win. We have to score three goals and our aim is to do just that while remaining tight in defence.
"If we play as we are capable of doing in Monaco, I still believe that we have a real chance to progress.
"We want to disrupt their rhythm and try to score as early as possible.
"It's 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 last week, I think there's a chance we can still progress.
"We have to believe in yourselves. 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."
