Arsene Wenger: Fear factor will weigh heavily on Olympiacos

The Greek champions are favourites to advance through to the knockout stages of the Champions League as they host the Gunners in a Group F showdown — with Wenger backing his side to be a danger in the latter rounds if they come through this stern test.
Having won 3-2 at the Emirates Stadium back in September, Olympiacos can afford to lose to Wenger’s side and still progress. Arsenal must win by two goals, or by 3-2 or better, to reach the knockout stages for a 16th straight season but Wenger feels they can get Olympiacos panicked if they play at their best.
