Ronnie O'Sullivan admits he must improve to stand a chance against Mark Selby

Ronnie O’Sullivan felt he “got lucky” on his return to competitive action at the Masters after a battling 6-5 first-round victory over Mark Williams and is “miles away” from top form, but hopes to be able to build some momentum at Alexandra Palace.

The 40-year-old had taken some time off following the World Championship in April, where he lost in the quarter-finals to eventual winner Stuart Bingham.
