Luke Littler has played 10 sets so far at this year's World Championship - and won them all

World number one Luke Littler produced a dominant performance to book a spot in the last 16 at the PDC World Championship, but fourth seed Stephen Bunting became the highest-ranked player to exit this year's tournament.

Littler averaged more than 107 and lost just three legs in a 4-0 win over Austria's Mensur Suljovic, demonstrating why he is the man to beat at Alexandra Palace.

The 18-year-old from Warrington is bidding to retain his PDC world crown - a feat that has not been achieved since Scotland's Gary Anderson won back-to-back titles in 2015 and 2016.

Littler was seeded to meet Bunting in the semi-finals, but the world number four was defeated in a deciding set by world number 63 and fellow Englishman James Hurrell.
