Former England and Arsenal footballer Paul Merson says it "sickens" him when he sees former players and managers in gambling adverts.
Merson is campaigning for betting laws to be changed as part of an upcoming government review.
Last year he made a BBC documentary about his gambling addiction and the industry, saying adverts are a "major trigger".
"I see people in adverts and they are rich," Merson said.
The 53-year-old Merson, who had a 21-year league career, added: "I could understand it if they were a League One or League Two player and had not earned much from the game, but the people doing the adverts are multi-millionaires.
