Former England football captain Tony Adams has led the tributes to Peter Kay, co-founder of the Sporting Chance rehabilitation clinic, who has died aged 52.
Kay worked as a mentor to Adams and players including Joey Barton, Paul Gascoigne and Paul Merson at the clinic, which helped sports people deal with alcohol, drugs and gambling problems.
Adams said: "Peter was my friend as well as a professional colleague and I am saddened by this news. He played a major role in changing perceptions and lives."
Kay helped Adams found Sporting Chance 13 years ago and worked as chief executive until 18 months ago when he stepped down due to illness.
A statement from Sporting Chance said: "As a result of Peter's work, there are now many sporting figures who are in good recovery, enjoying fine careers and living life well."
