Forget the fate nonsense and the bravado: Wenger's failure in the Champions League this year is clear - and should be roundly criticised.
He will trot out the usual "It makes no difference, if you want to be the best you have to beat the good teams at some stage" bullsh*t. And it's just as inexcusable - and naive - as it ever was. It's a cup competition - a cup in which Arsenal are by no means the best team. The longer you stay in the competition - even if just a single round more - the more chance you have of fluking an easier run to the final. Which is what this team will need to win it.
Wenger would prefer to think no such practical strategy exists because a) of his delusion that this defensively-impotent Arsenal side can genuinely compete with Europe's top-class teams; and b) because he has once more screwed up the group stages. He is an arrogant idiot. This is a failure with a clear consequence: to come second in the group is to invite the possibility of Barca. Which is what has happened. We have quite literally asked for it. Given that they are obviously the best team in the competition, and that we have now ended the possibility that someone else might upset them for us, this is not just foolishness in the extreme, but a gross competitive error.
