Some of what Sean is saying does have at least some truth to it. The gap between mid table teams and those at the top has closed. Mid table teams have been able to get results when the top teams have been just slightly below par. Chelsea, Man U, and us have seen this so far. Even Arsenal dropped points at Blackburn.
And, your conclusions maybe right, but cannot be proven for quite a while yet. If at the end of the season we are struggling to keep a CL spot, then I'll say you were right, and baring really unusual circumstances, I'll be calling for Rafa's head. But after 11 games, just way to early to come to any conclusion.
My biggest fear this season was that we had the squad to challenge, but would have our usual slow start which would give us too much of a hill to climb. When you realize how many new players were coming in, this was a real concern. But in many ways having a flying start made things worse. We looked like contenders who just ran out of steam, so now even our own fans are writing us off. But while form has deserted us, grinding out results has not.
If we are still playing with our current form come January when hopefully we have key players back, and we are not at least keeping pace, I'm sure I'll be questioning Rafa's wisdom, but right now with form off, key players out, we are still in contention. So I'm going to keep the faith.
