Former Aston Villa striker Stan Collymore says young footballers are "milked like a cow" and are not given enough help off the pitch.
Collymore, 45, wrote an open letter to Villa midfielder Jack Grealish this week after Grealish was reportedly involved in an all-night party.
Collymore told BBC Radio 5 live: "I am concerned. Where are the mentors? Where are the people in the dressing rooms?
"Footballers are produce, there to be milked like a cow."
"When they are surplus to requirements they are dispensed with," he added.
Collymore called his £7m move to boyhood club Villa in 1997 "a disaster" in his open letter, and highlighted some of the issues facing many young footballers.
