Theo Walcott starts up front alongside Olivier Giroud in an attacking Arsenal line-up for their crucial Champions League tie at Olympiakos tonight.

A Gunners' victory by any margin other than 1-0 or 2-1 is required to stave off group-stage elimination.

Arsenal manager Arsene Wenger believes his side could be "dangerous" in the latter rounds of the Champions League - so long as they get there.

"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 Olympiakos.

"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."

Teams

Olympiakos: Roberto, Elabdellaoui, Siovas, Da Costa, Masuaku, Milivojevic, Kasami, Seba, Pardo, Fortounis, Ideye.

Arsenal: Cech, Bellerin, Mertesacker, Koscielny, Monreal, Ramsey, Flamini, Ozil, Walcott, Campbell, Giroud.
