Not chronological, though.
I usually check there.
I check wikipedia 'List of Italian/Spanish/etc... summer transfers 09' about once a week aswell to whats going on everywhere else.
Also, I love that Owen is going to United. I said a few months ago that if anyone was going to help Owen become better than what he is now, and somewhat like his old self, then it would be us. So yeah, really happy and it's a fucking bargain.
