Arsenal will be hot favorites for this tie, having gotten their European ambitions off to a good start with a 2-1 win at Montpellier a fortnight ago. Olympiakos on the other hand have already dampened their own hopes of qualifying from Group B by losing their opening match 2-1 at home to Schalke.

The Gunners though could be without Mikel Arteta, as the 30-year-old Spanish midfielder has taken a knock and is suffering with an ankle injury. He will have a fitness test prior to the match to see if he will be available.

Meanwhile boss Arsene Wenger has confirmed that goalkeeper Wojciech Szczesny will not be available and may be out for another "2 to 3 weeks" with the thigh strain he suffered during Saturday's loss to Chelsea.

Tomas Rosicky is still out with his achilles injury. But Jack Wilshere could be an option as he played in his first game in over a year on Monday, taking part for just over an hour against West Brom in the Gunners' under-21 side.

Wenger said of the player, "He came through it all right. There was no reaction. We are pleased but it is now down to taking the right time to ease him slowly back. We are all very happy. He must be exceptionally happy, but he has been out for 14 months."

Manager Arsene Wenger will not be taking the Greek side lightly. The Gunners also played Olympiakos in the Champions League group stages last year; winning 2-1 at the Emirates, but suffered a surprising loss 3-1 away in Greece.

"Olympiakos are already in a position where their backs are to the wall because they have lost at home and in this Champions League when you lose at home it is very difficult," said Wenger, according to BBC Sport. "They are highly motivated to know they have to give everything to make it through. They are experienced and basically it is the same team [as it was] at the back of last season. I think they had a difficult start against Marseille and after became stronger and stronger through the competition last year. It looks similar this year - they had a difficult start at home against Schalke and if you analyze their team it is 90% the same as last season."
