The final whistle goes and the Gunners cling on for the victory.
Djebbour goes into the book after a late tackle on Arteta.
Arsenal make another change and this time it is Kieran Gibbs taking the place of Arshavin.
Another Olympiakos substitution with Marko Pantelic on in place of Fuster.
Djamel Abdoun and Francois Modesto are on as they replace Mirallas and Pablo Orbaiz.
The moderate Chamakh goes off and is replaced by Robin van Persie.
Arshavin causes more problems and wins a free-kick 25 yards out after a foul by Fuster. The latter goes in the book.
Arshavin tries to work the ball onto his left side but he is unable to get a shot away in the Greek box. Chamberlain goes off and is replaced by Aaron Ramsey.
Holebas goes in the book after a foul on Chamakh.
A lively and open first half and Sky Bet make Arsenal 1/4 with Olympiakos on offer at 12/1. The draw is 7/2. Chamakh is 6/1 to get the next goal while the impressive Mirallas is an 8/1 chance. Alex Oxlade-Chamberlain is 10/1 to add to his opener by netting next.
That is it for the first half and the whistles goes.
Sagna gives the ball away in midfield and Rosicky chases back only to foul Mirallas right on the edge of the Arsenal box and he goes in the book.
GOAL SANTOS: A first goal for the Gunners as he pounces on a rebound to fire home. He did much of the build-up work too as his cross just fails to find Chamakh but he is alert enough to pick up the second ball and score from close range.
GOAL OXLADE-CHAMBERLAIN: No surprise as the teenager has impressed so far. He collects the ball on the edge of the area, beats one defender and calmly slots the ball into the corner with great aplomb.
Aundrae Wood says: "It cannot be said enough that the Arsenal squad has a decided lack of depth. To start Emmanuel Frimpong in a home champion's league encounter underscores that that very point...my hope as an Arsenal fan is that we start fast to get the crowd involved and hopefully gather momentum. We are going to need all the help we can get tonight."
Thanks to Jack Holt, who says: "im going for a nice 2-1 victory for the gunners, with chamakh and arshavin scoring."
Arsenal remain strong 8/15 favourites with Sky Bet despite their injury problems with Olympiacos 11/2 to win at the Emirates and a draw 3/1. In Robin van Persie's absence, Marouane Chamakh is 5/1 to break the deadlock while Kevin Miralles is rated as the visitor's biggest threat at 10/1 to score first.
