"There's always something happening and most of us are all involved in football anyway. In my case they might phone to ask about a player in the MLS or if something has happened with someone else, so I speak to a lot of the guys a fair bit.
"There's Big Al (Hansen), Kenny (Dalglish), Beards (Peter Beardsley), Barnesy, Kevin McDonald - I'm still in regular contact with lots of the boys.

"It's easy to say I will but you don't know. I do my best every day that I come to work. If things happen then great, if not then that's fine too.
