Once Jonny Clayton was selected it was a weight off his shoulders and he could just go and express himself.
He knows he is reliable in the Premier League. He can be confident going there too.
He gets the Premir League and knows how to play the format. You know you can rely on Jonny in the Premier League.

Luke Littler doesn't need anything to spur him on but he loves a record.
Let's not forget, he was a long way behind Jonny Clayton at one stage but now he has a chance to wrap up top spot with a week to go.
Credit to him. It hasn't gone all his own way in this year's tournament and he hasn't been a crowd favourite.
After a slow start to his Premier League campaign, Luke Littler is flying once again.
Last week in Leeds, he beat Luke Humphries to claim a third successive night win and a record-equalling sixth victory of the season.
Can he set a new record of seven wins tonight?

Boos for Luke Littler as he's being announced.
Littler v Clayton
Luke Littler talking to Sky Sports: "I always say concentrate on the first game for those two points but tonight has a lot riding on it because I know if I beat Jonny [Clayton] then top spot is confirmed. I won't put any pressure on myself but obviously I want to get past him and put on a good performance.
"If I get past this first game then in the semi-final and final I will be able to play with absolute freedom. I feel like I am playing well at the moment so if I get through you might see some crazy checkouts in the semi-final."
Littler v Clayton
Jonny Clayton talking to Sky Sports: "It was nice to have a run [in the Players Championship] but to be fair to Andrew Gliding he battered me off the board. It was a nice run and confidence is up. Hopefully I can get two points and maybe five.
"You always play to win. That is always my motto anyway. Even though I've qualified I still want to win the night and there is still £10,000 to win and that is big money."
Clayton v Littler
Luke Littler and Jonny Clayton can relax.
They already know they'll be looking to become two-time Premier League winners on 28 May.
Up for grabs, though, is top spot and bragging rights.
