The Transfer Window Pod
These lads record every Mon, Wed, and Fri. I listen religiously. They're incredibly knowledgeable and embedded in the game with contacts galore. Great info. Great personalities. Check them out.
Transfer Talk Pod
Recording only during transfer windows, the folks from Sky discuss almost every single real and rumored transfer in the major European leagues. VERY good. But also not year-round.
NEWS NOWYep, they're listed above as well. Again, I like this site because it's a collection of sources from around the web. It also automatically refreshes itself. AND, if you click on an individual PL team, you can see articles about transfers for that team alone. It's great to keep tabs on your club's transfer business (or lack of).
