Chinese star Ding Junhui revealed he is under so much pressure to win a maiden world title that he wished he had extra-terrestrial powers. World number nine Ding has never got beyond the semi-finals of the world championships, the 2013 edition of which gets underway on Saturday in Sheffield. And unlike 2012, when there were four Chinese players in the main draw, Ding will be his country's only representative this time around. That has only increased the expectations.
