DescriptionFormer Liverpool striker Stan Collymore has hit back over comments Piers Morgan's "man up" comments regarding mental health.The ex-footballer appeared on ITV's Good Morning Britain to talk about mental illness after Morgan suggested that there shouldn't be a stigma surrounding people who have a "stiff upper lip".The TV presenter has said that he isn't convinced by the trend of "male public soul-bearing", the Mirror reports .Collymore became the first English football to open up about his battle with depression, but during his time at Aston Villa, he was told that fans wouldn't sympathise with his health by a manager in 1999.The radio broadcaster, who made 81 appearances for the Reds, visited the Roehampton Priory mental health hospital, said: "I spoke to the club, spoke to the manager and we've kind of made our peace in the intervening years."But it's 'how can someone earning X amount of money a week be depressed'."At the time in professional football that was the old prevailing attitude."Morgan earlier this week tweeted: "I’m not convinced by this new trend of male public soul-bearing. Time for our gender to get a grip, methinks. Life’s tough- man up, " which caused a lot of anger on social media.He continued by saying that people in the modern era are now being led to believe "all the rough and tumble of modern life is part of mental illness",However, Collymore disagreed with his opinion and speaking on Good Morning Britain said: "If I stood in front of a group of people, lets call them flat earthists, who would say how can depression exist when you have material wealth, I would say can I get cancer, can I get aids, can I get ME?
