RONNIE O'Sullivan will take on Neil Robertson in today’s BetVictor Welsh Open snooker final in Cardiff after beating Joe Perry 6-3 in his semi-final.

Australian Robertson beat Northern Ireland's Mark Allen 6-4 to reach his second final, which begins at 1pm this afternoon.

Speaking after the semi-final, O'Sullivan compared Robertson to RoboCop.

"I have watched him through the UK Championships and he never showed emotion through the whole tournament, said O'Sullivan ahead of the best-of-17 final.

"It shows what an unbelievable professional he is. He is Robocop, he is like the new Steve Davis or Stephen Hendry."

Robertson says O'Sullivan is the favourite for the title.

"I don't mind flying under the radar," he added. "It is nice, I can be the underdog."
