If Luke Littler plays like he does earlier then there is no doubt that Gerwyn Price will have to up his level.

Well Chris, we're about to find out as both players have made their way out to the oche.

I've seen nothing to change my mind on Luke Littler being the winner tonight.

I don't doubt that Gerwyn Price can beat him though - he's got the game to beat him, it is just about doing it at the right time.

Gerwyn Price just has to start well and stay close because we've seen what Luke Littler can do in the past couple of rounds when he gets ahead.

Luke Littler talking to ITV4: "I've just been chilling. Me and Gerwyn always bring the best out of each other and hopefully we can have another good game tonight.

"Some players might think I do [act differently against Gerwyn Price] but it is just whatever happens on the night/day. I just need to play well and get him out of the way.

"If I'm in the lead maybe I'll give him a little bit back. I just want to get into the lead and have a quick start again.

"You can't look at any trophy until you're in the final - that is the same in every tournament. I'm glad to be into the semi-finals for the first time."
