Its quite simple really.
When a club, in this case Burnley come in with a bid - we turn around and get this, say no.
Then the player gets pissed off, potentially disrupts the dressing room (not that it was ever seemingly 'collective' anyway) hands in a transfer request and we sell him anyway to keep harmony.
How do you know what was going on at the club? I would have loved to have kept Austin, but perhaps it just wasn't viable?
