Arsenal in Champions’ League

Just been watching the Champions’ League Draw on Sky Sports. You’ve never seen so many containers of balls in your life. I won’t begin to try to explain how they made something so simple so complicated. I still don’t quite understand red and blue groups – something to do with A-D being red and E-H being blue… I think.
OK so Arsenal are in Group B and will play Inter (who were forced into our pot), Dynamo Kiev and Lokomotiv Moscow.
Quite an east European lineup!
But the question is which groups play on Arsenal’s night, since that’ll effect how likely it is that Arsenal’s games get shown.
Man Utd have got Rangers, Panathinaikos and Stuttgart.
Chelsea have Lazio, Sparta Prague and Bekitas
Celtic have Bayern Munich, Lyon and Anderlecht
