Comfortable Arsenal - us??

I assume Liege and Twenty are roughly equal in ability. Arsenal has gone to Holland, won comfortably 2-0 and have absolutely no worries about the home leg. We on the other hand are just as likely in our home leg to lose to a fluke goal, own goal or some other disaster. What i am trying to say is that, despite all the good pre season form, we can't and don't put away these lesser sides. I'll end by saying that I am also pessimistic about todays visit to Sunderland. If Diouf scores the winner.............!!!!
