BREAKING TEAM NEWS
Francis Coquelin starts in midfield for Arsenal. Laurent Koscielny keeps his place in the side and Mikel Arteta has passed a fitness test so plays in midfield. No Olivier Giroud in the starting XI.
I really don't understand why Giroud isn't starting. Surely the guy needs games, and tonight seems an obvious one to play him in. I have to say, I also thought it was odd that he didn't come on earlier against Southampton, as surely that was a golden opportunity to play him with no pressure, at home, in a game where we were banging them in left, right and centre.
Also, no Mertesacker again?? - what has the guy done wrong? he's been our best defender this season, and was outstanding at Citeh, yet was dropped for Chelsea? and not even reinstated tonight either?? - yet, presumably he'll be back in the team against West Ham?? - I reckon this needless rotation at centre back will cost us this season.
I don't get Wenger. I really don't.
Don't get me wrong, I still think we'll win comfortably; Olympiakos are pants! (I assume)
