Naw he's not. Just called him and got:
"You've reached the voicemail for Jack Ross, manager of the greatest football club on earth. I'm not available right now but if you'd like to leave your name, number and short message, I'll get back to you as soon as I can. Unless you're calling on behalf of Dundee FC in which case, I've already said no so please f*ck off and let me enjoy my holiday"
