Even if we're 100% perfect from now on, winning every game, Arsenal will have to drop 8 points (taking GD into account) for us to win it. Now, I have no doubt that Arsenal will drop points; they'll have a daft defeat or two, and a few draws. But there's no way I can see us not dropping more points. We're just too inconsistent this season. Brilliant against Liverpool (though looking at the way they're playing at the moment, that win may not be all that special), back to frustrating at Newcastle.
And all the above isn't taking Chelsea into account.
