The best site to follow the action as it unfolds, I find, is the Guardian sports section, and their minute by minute update. The scrolling, sprawling update reflects the chaotic nature of the day with it's updates from managers, players and fans, sometimes completely erroneous, sometimes absolutely hilarious.
Stuff like this;
12.53pm: "My father is the cleaner at Southampton's training ground," says Robin White. "There's a Bulgarian lad there called Robko Byalov being put through a medical, apparently."
How vague and how random!
Here's hoping Sunderland cause a splash and land someone decent before the 5pm deadline!
