The former Burnley and Man City star gave a talk to eggheads at Cambridge University.

“Don’t get too high. Don’t get too low”
Joey Barton
In his speech, Joey, 35, insisted he had “no doubt” that he would have captained England if he had been more mature – despite only winning one cap.
When asked who his favourite philosopher was, he chose Epicurus, an ancient Greek who taught that happiness could be achieved through the pursuit of simple pleasures and moderation.

“Don’t get too high. Don’t get too low,” said Joey, who was once jailed for assault.
“Don’t get too frustrated when things don’t go well.”
Then he added: “If I’d have learned that at 21, as opposed to 31, I’d have captained England. No doubt about it.”
