Arsenal begin their Champions League campaign tonight with a trip to France to take on Montpellier at the Stade de la Mosson. Kick-off time is at 7.45pm and the match will be screening live on UK television from Sky Sports 2. Here's the team news ahead of the game... Arsenal will be without their first-choice goalkeeper Wojciech Szczesny. The Polish international has an ankle injury which will keep him out of the Group B opener. With Lukas Fabianski also injured, reserve stopper Vitto Mannone is likely to deputise in goal, with 21-year-old 'keeper James Shea on the bench. Russian international winger Andrey Arshavin misses out, but Abou Diaby (hip) could be fit as he left out to France with the rest of the 18 man squad from Monday afternoon. Midfielders Tomas Rosicky (hamstring), Jack Wilshere (ankle) and Emmanuel Frimpong (knee) are all still missing, along with long-term absentee Bacary Sagna (broken leg). Veteran Arsenal boss Arsene Wenger will watch the game from the stands as he is still suspended from the touchline following an incident against AC Milan last March.
