I don't think timing is always an indicator of priorities, Brighton and Wight might be far more willing to get this done than other targets, so it naturally comes to a head quicker.
That's my hope anyway. Reports from most Arsenal journalists, including ones who've maintained for a long time that we're after another RCB, have indicated that we're after players in half a dozen positions and none of them have thrown in the usual caveats that you hear about selling first or limited funds.
