Porto will be fine for Arsenal, they've never won a CL game in England have they?
Not sure but last time we played them in the group it was a 2-0 loss in Portugal but then we thumped them 4-0 at home.
Crap - mind you AC have been a bit dodgy in recent times
Arsenal's draw should be easy enough, can't see either Italian team hassling Chelsea/Man Utd too much, they're just too slow. Although Inter vs Chelsea is definitely the biggest game of the round, it'll flatter to deceive though.
