Dictionary: gaffer"So we're sitting there waiting for the gaffer (Sir Alex Ferguson) to come in and speak to us, and I'm literally sitting right next to Roy Keane. The dressing room is so small that our legs are almost touching. There's no space at all. It's dead quiet. All of a sudden, you could hear this little vibration. Very soft. Roy is looking around the room.
"I realise it's me. It's my cell phone. I left it on vibrate, and it's in the pocket of my pants, stuffed in the clothes bag that's hanging right behind Roy's head. Roy can't find where the noise is coming from. Now he's looking around the room like a maniac."
