Ronnie O'Sullivan says he no longer 'breaks down mentally'

Five-time world champion Ronnie O'Sullivan talks to BBC Sport's Jamie Broughton about focusing on snooker, rediscovering his love for the game and his ultimate ambition.

The 37-year-old acknowledges he has faced a number of difficult times in his career but believes he is now "stronger for it" and says he "owes everything" to sports psychiatrist Dr Steve Peters.

Having won the World Championship in 2012 and 2013, the Essex-born player - whose new book Running details the highs and lows of his career - says it would be a "dream" to match or pass Stephen Hendry's record of seven world titles.
