Mark Selby is feeling back towards his best after booking semi-finals spot

Mark Selby admitted he doubted whether he would ever return to the one-table set-up at the Crucible after completing a 12-7 win over Neil Robertson to book his place in the World Championship semi-finals for the sixth time.

Selby suffered a crisis of confidence in the wake of his third world title win in 2017, losing his world number one ranking as he won just two tournaments in the following two years and crashed out in the early stages in Sheffield.
