After a hugely disappointing first CL game, Arsenal are back at it today, at home, against Olympiakos. Olivier Giroud is, of course, suspended after that first leg, and Flamini and Arteta are out. Francis Coquelin, however, is back in contention after recovering from a minor knee...something or other that wasn't too serious.
Arsenal have sort of lost their cushion by dropping those points to Zagreb - this is a game where they need maximum points, considering that their next two CL games are against that plucky team of underdogs, Bayern Munich. The Greek champions are undefeated in their league this season, but lost to that Bayern side in the first round of CL games; hopefully Arsenal can send them home pointless again today.
