The summer transfer window is open, or it's not. This bit from bbc.co.uk attempting to explain the timing surrounding the summer transfer window is awesome.
--- LAST UPDATE: 29 MAY 2013 ---
The key quote reads thusly: "The summer transfer window reopens on 1 July, but clubs may announce signings before then."
Which, in a roundabout way, explains how erstwhile Borussia Dortmund standout Mario Gotze can be Dortmund's property, but then betrothed to Bayern Munich, and therefore held out of a freaking Champions League final with a phantom injury.
Some business, this.
So back to the wires we go, trying to guess the unguessable as the transfer rumors continue to ebb and surge like Fitzgerald's ceaseless tide.
