It was great to see that most eloquent of sport journalists, Paul Hawyard, mention Undercover Sport in his Daily Mail column yesterday.http://www.dailymail.co.uk/pages/live/articles/columnists/columnists.html?in_page_id=1951&in_article_id=562872&in_author_id=342
The link is above if you missed it - the Charles piece is the third story down, after the picture.
As he wrote, Gazza's tackle on Gary in that 1991 Cup final "was like a starting gun in a race to self-destruction", such has been the subsequent decline of both players.
When I met Gary, several weeks ago, he looked good and had been sober for many months.
Yet he admitted he was still, and always would be, a recovering alcoholic and, at any moment, one drink would smash his dam of sobriety and submerge him.
Sadly, that is the way things subsequently turned out. That one drink led to Gary drinking himself into oblivion and then repeating the pattern day after day, for weeks on end.
When I had met him, he told me: "I don't know what makes me drink. I've asked myself that question over and over again, and if I knew, my life would be easy.
"I've been to alcoholics anonymous, I've been to therapists, but I still have these problems."
As I mentioned in the previous blog, Roy Keane has been something of a saviour for Gary.
I am sure he would hate to be described in those terms and that he would be reluctant for this story to even get into the public domain, which speaks volumes for the man.
Whereas the rest of the game seems to have turned its back on the fallen former England star, Keane has been there for him since he was released from prison last May.
Despite the pressure and workload that being a Premiership manager must inevitably bring, Keane has offered support, help and advice to his former housemate.
Yet, as Gary himself would acknowledge, he is the only one who can tackle his drinking problem and get his life back on track.
Sadly, that is something he has not been able to do, since his days as a rising first-team star at Nottingham Forest, through to his days with Villa, Benfica and West Ham and then during his time on civvy street.
Last month, Gary's drinking got worse and worse until desperation overcame pride and he called Keane for help. Keane immediately arranged a place at an alcohol rehab centre in the north east, where Charles is now.
When he is ready, he will come back out into the world. He realises that he needs a new purpose in life to fill the void left by his retirement from playing in 2002 and hopes that coaching could be the answer.
Whatever happens, he knows that Keane will be there to help.
