Rock is expecting 'fireworks' from his tie against Aspinall as the rising Northern Irishman takes on 'The Asp' who has reached two major finals this season and both have been standouts this year.

"I know there will be lots of fireworks because Aspinall will be ready for that game and I will be ready for that game," said Rock as per Sky Sports.
"There will be a lot of good darts. Then I know I'm hitting them at the right time I like to show emotion. I'll be looking forward to that game with Nathan because obviously it's a bigger game than the European Championship and it will be a great game regardless.
"It will be electric from the off against Nathan. He's been a two-time semi-finalist in this competition two years in a row so I know what he can do. I need to play my own game and forget about what I'm there for.
"I'd say it's going to be a very tight game. He's going to look for revenge for the European Championship and I'm going to do my best to make sure it doesn't happen."
