I think the problem for a lot of LoI teams in Europe (particularly ourseleves it has to be said) is that they lack the necessary concentration to stop giving up chances against teams with a bit of quality and get punished severely for it.
you can switch off for ten minutes against most teams on a weekly basis here and get away with it as they won't be clinical enough to punish you. This forms bad habits which are so ingrained it is almost inevitable that they come to the fore in Europe.
With that in mind I can't see us getting through next week.
