One factor not yet mentioned is that we were intentionally I think, very right sided. We never really had a left wing. Warnock had all sorts of space to push up often, because we had no wing in front of him and therefore no opponent. It's why Warnock was pushed into forward positions much more than Hutton. It's also why albrighton saw quite a bit more of the ball than anyone else in the attack. He did some very nice runs, passes and crosses and some less attractive crosses as well. That's why he got such mixed reviews.
Warnock looked very vulnerable on defense and wasteful on offense (I think some thought he played well because he was so far forward so often, but as I said, I think that was only because nobody played left wing at all in the first half, and gabby only stayed wide part-time in the second half.) I don't know if having so much time and space left Warnock disoriented or what, but my he was wasteful.
