He's just someone who makes some money from being an Arsenal pundit.
Maybe he has links into the club, but those links (you would think) would be plugged up by the club if they didn't want private info getting out. But then, you would have though someone with as close links to the club, like Wrighty, Smudger, Dixon, Keown etc etc would know more....and their guess is as good as anyones...
All I know is that he's talked absolute rubbish whenever I've listened to him.
