Sunderland director Niall Quinn has hit out at the Professional Footballers' Association's attempt at providing information on how to deal with depression in the game.

The apparent suicide of Wales manager Gary Speed prompted the PFA to release a guidebook on how to cope with personal problems including depression, alcohol and drug abuse.

Although the help book has been sent to 4,000 members of the PFA, the former Black Cats chairman doesn't believe that enough is being done for professionals who are no longer in the game.

"I have chatted about this all week since Gary's death, and certain things have been pointed out to me," the Daily Mail quotes Quinn as saying. "Things like the amount of marriages that break down when football careers are over, and bankruptcy.

"Our union sent a book out to everybody last week. What's that about? I think they should do an awful lot more. They're a very wealthy organisation. They back people like [Carlos] Tevez for doing what he did [at Manchester City] and protect him and say he shouldn't be fined and all the rest, and then send a book out.

"Depression doesn't just kick in in the Premier League, it kicks in in the fourth tier, the third tier, the Championship. And it doesn't manifest itself the day somebody quits. It could be two years, three years, four years after. I think they should do an awful lot more than go on telly saying they sent books out."

Quinn's comments follow the jailing of former Manchester United player Ronnie Wallwork for being found in possession of stolen goods.
