Ronnie O'Sullivan was embroiled in an angry exchange with referee Olivier Marteel as he took a 5-3 lead in the opening session of the World Snooker Championship final against Judd Trump.

Marteel appeared to admonish O'Sullivan when the six-time champion returned to his seat after failing to get out of a snooker in the eighth frame, prompting O'Sullivan to jab his finger and respond that the official "saw nothing".
