I wouldn't really claim to be a football fan, I'm a City fan.
I do listen to the odd game on radio when driving about, (I go to other grounds and watch it on tv too if the fancy takes me) but I've never heard of Alan Green. I didn't even know he was a commentator. It's possible I've heard him, but I don't listen too much as most commentators seem to spout ****e rather than just inform you what's happening on the pitch. I don't know the other teams players, so often radio commentary's even less use to me.
Ironically, I noticed MOTD2 had started so I Sky plussed it to skim through, and when I put it on, at first I wondered why John Prescott was there. I can't say the odd little man looked or sounded familiar.
