After the game against Stoke, Arsene Wenger admitted the low attendance is the price that the Gunners must pay for their disappointing Premier League campaign, where they now sit in sixth, 13 points behind fourth placed Spurs.
"There is some extra pressure to do extremely well in this competition, but that is part of being where we are".
This will be Arsenal's first European quarter-final since 2010 and, having previously reached seven quarter-finals in the first 14 years of his tenure, Wenger is convinced that the club's supporters will turn out in force tonight.
Arsenal have scored nine goals in their last three games in comfortable wins over Stoke, AC Milan and Watford since then, but attendances at the Emirates have dropped.

"We are going to give our best to win those games and also see where we are in Europa League", adding "It is important to have a good result for the second leg".
