I must admit that the defence hasn't really been tested, and it is a worry. People shouldn't underestimate Olympiakos as they are a good team, unfortunately i'm not sure they fully turned up.
Celtic is a good game to have as they have an important playoff, although this could count against it as they might not risk players. I expect us to take it seriously like a real match.
I do agree that we should have had a competitive team from Germany, Italy or Spain.
