Arsenal goalkeeper Wojciech Szczesny is not getting complacent about their chances of qualifying for the knockout stages of this season's Champions League.
Szczesny told arsenal.com: “We know that we only need one point from our last two matches to qualify for the last 16, but we know that we have not made it yet. We’re playing at home in front of our fans and we’re confident that we can put in a good performance and qualify.
“We all know that our last match in the Champions League at home to Anderlecht was disappointing. But we must put that behind us and we’re all ready to bounce back against Dortmund and hopefully get a place in the last 16.
“Dortmund are a very good counter-attacking team. They press your midfielders very well and are quick to attack as soon as they get possession. They’ve got some great finishers as well, so going forward they are very strong."
Where it not for a disappointing second half performance where Arsenal let a 3-0 lead slip to Anderlecht, they would already have their place in the knock-out stages of the competition secured.
Szczesny, however, is a doubt for the game with Dortmund after being substituted through injury during the weekend's defeat to Manchester United at the Emirates Stadium.
The two sides are not in the best of form with Dortmund still struggling for momentum in the Bundesliga, but their form in Europe has been a high point as they're currently top of the group.
If Arsenal are to qualify as group winners, they have to take all three points against a Dortmund side that beat them on Matchday One, and also left the Emirates Stadium with all three points last season. It should be an interesting contest.
