See my previous reply.
The qualifying rounds are ill thought out by UEFA. The competition is too big, and this is just a way of squeezing the last droplet of cash out of it, to the detriment of the quality of the competition.
I don't think us starting it so early was the cause of our problems though. We treated them as pre season games anyway. Our problem was so many new faces playing together in a team lacking balance and direction. Oh, and we didn't have a proper striker either.
