Mr Stewart, who began his professional career with Blackpool and also played for Manchester City and Liverpool, told the Mirror an unnamed coach abused him daily for four years.
It comes after two ex-Crewe players said a club coach abused them as boys.
Eleven people have contacted Cheshire Police since one of the men, Andy Woodward, went public with his story.
Mr Woodward and Steve Walters spoke of being abused at the hands of coach Barry Bennell, who was jailed for nine years in 1998.
Professional Footballers' Association chief Gordon Taylor said he expected the number of players coming forward to rise.
Mr Taylor said: "We're now seeing more and more players come out and having the confidence to come out," he said.
