"A year ago, if you'd have asked me who was one of the mentally strong players within the England side, I would have said Jonathan Trott. He seemed to be very self-contained and in his own little word even if he had his own idiosyncrasies that used to drive the opposition mad. But I had no idea that he was fighting an illness like this."

Journalist and former England cricketer Angus Fraser spoke to Joe on the show earlier about current England player Trott who has left the team with a long-standing stress-related illness.

Fraser believes Trott has made a brave decision to be very public about his situation, given the continued ignorance about mental illness.

Meanwhile, Australia cricketer David Warner's comments at a press conference shortly before Trott left the Ashes has been pilloried. Warner had said: "The way that Trotty got out today was pretty poor and weak."

Fraser touched on that controversy.

"I don't think you can blame David Warner for the fact that Jonathan Trott has gone home. But it will be used a stick to beat David Warner. It's not the worst thing that has ever been said about a fellow athlete by someone."

Fraser also believes the high-pressure environment of test cricket and elite sport intensifies situations like the one Trott is embroiled in.   

"The hardest thing in elite sport is to get your body to do what you want it to do, without your mind interfering," he said.
