Ali Carter 'not enjoying' snooker

World number 11 Ali Carter says he is considering retiring after the World Snooker Championship, external because of health reasons and a diminishing love of the sport.

The 32-year-old, who last won a ranking tournament at the Shanghai Masters in September 2010, reveals that his lack of form and battle with Crohn's disease, an inflammatory bowel condition, means it is hard to stay motivated.
