Wenger believes Arsenal will be 'dangerous' IF they progress in Champions League
Arsenal boss Arsene Wenger believes his side could be "dangerous" in the latter rounds of the Champions League - so long as they get there.
The Gunners face Olympiacos tonight knowing that even a victory may not be enough to see them qualify from Group F.
Having lost three of their opening group matches, including a 3-2 home defeat to their Greek opponents in September, Arsenal go to Piraeus as outsiders to progress.
They must beat Olympiacos by two goals, or match or better the result from their previous meeting, to seal qualification from their group for the 16th consecutive season.
And Wenger feels that, if they can get the required result in south-west Athens, Arsenal can sustain a challenge to win the competition - even if he admits there are a number of teams who are more fancied.
"Of course we can be dangerous if we go through because we come from far back," he said.
"Overall if you look at the numbers since the start of the Champions League group stage, we have played with 10 men in Zagreb, we scored an own goal at home to Olympiacos.
"Every single game we were a bit unlucky but if we get through we will be dangerous that is for sure.
"At the moment we have two or three super-favourites and whoever gets through tonight or tomorrow will have to chase them."
If Wednesday's game at the Karaiskakis Stadium takes plenty of twists and turns as both sides look to join Bayern Munich in next Monday's draw, Wenger knows his players must be able to alter their gameplan on the pitch.
"We have to put every scenario in our head, it is important we focus on the performance," he added. "The results come if we play well so lets focus on that. When the goal comes I don't know but if we play well we have a chance to score.
"Mentally, you prepare yourself to adapt to every situation and give the right response to every situation you face.
"We will have to adapt to what is happening on the pitch and to all of the scenarios, accept them and respond."
Wenger has no fresh injury concerns ahead of the game and is likely to field the same starting XI that secured a 3-1 victory over Sunderland on Saturday.
Theo Walcott is again likely to only make the bench as his comeback from injury continues, while Mathieu Flamini and Aaron Ramsey have been backed to continue their partnership in the heart of midfield.
"Midfield is important in games like this," Wenger explained.
"Flamini and Ramsey will have to play an important part in a game of this stature but I'm confident that they can and will."
