Goalkeeper Wojciech Szczesny has warned Arsenal must not take qualification for the last 16 of the Champions League as a formality - even though they need just a point from their final two Group D matches.
The Gunners would have already been through along with leaders Borussia Dortmund, whom they host on Wednesday night, had they not thrown away a 3-0 lead against Anderlecht on Matchday Four.
As it stands, Arsenal are still in a strong position, five points clear of the Belgians with two rounds of fixtures left, which finishes away to bottom club Galatasaray.
Szczesny (above) though, insists there can be no complacency. "We know that we only need one point from our last two matches to qualify for the last sixteen, but we know that we have not made it yet," the Poland goalkeeper said.
"We are playing at home in front of our fans and we are confident that we can put in a good performance and qualify."
Szczesny, injured in the incident which led to the opening goal in Saturday's Premier Leauge match against Manchester United, will be hoping to recover in time for this week's European clash.
He added: "We all know that our last match in the Champions League at home to Anderlecht was disappointing, to only get a draw from that position, but we must put that behind us.
"We are all ready to bounce back against Dortmund on Wednesday and hopefully get a place in the last 16."
