Arsene Wenger insists victory over Barcelona will present Arsenal with a magnificent chance of winning the Champions League.
The Gunners meet the competition's favourites in the round of 16 first leg at the Emirates Stadium and travel to the Nou Camp on March 8.
Wenger believes that should they progress into the quarter-finals, Arsenal will be in a strong position to seize the ultimate prize.
"We want to win this competition and we know the only way to do that is to beat the super-favourites," he said.
"Barcelona are certainly the best team in the world at the moment.
"If we knock Barcelona out, we straight away have a good chance to win the tournament."
