Ralph Adams-Hale has everything crossed that he can keep his place in the Saracens side for the Gallagher Premiership final after coming off the bench in the comfortable 44-19 win over Gloucester in the semi-final.
The former Harpenden player has already had a special season, making his first appearance in the Men in Black's first team earlier in the campaign.
And while his selection in the 23-man squad has come following the injuries to Mako Vunipola and Titi Lamositelle, the 22-year-old is determined to prove the faith in him is justified.
"It was class to be on and for that amount of time as well," he said.
"I've been out for the last three weeks with a concussion so it shows a lot of faith in me from Mark that he is happy for me to come straight back in and play a semi-final.
"I really appreciate that vote of confidence in me but I now want to show him even more and prove it's not misguided."
While Sarries are regular visitors, it will be the prop forward's first appearance at Rugby HQ.
He was at St James' Park in Newcastle to witness the Heineken Cup success, and that is driving him on to be involved again.
"It was a classy performance," he said of the show against Leinster two weeks ago. "It was a complete performance and it was a beautiful thing to watch and so to be part of that and be part of an organisation that has done that is a special thing.
"Hopefully I'll be directly part of it on Saturday."
Saturday's win over Gloucester was not as perfect as that never to be forgotten night on Tyneside but Adams-Hale says he was happy enough with his 20-minute cameo.
He said: "It wasn't the best start but we rallied and broke them to get on top.
"And we didn't let off.
"There is always stuff to work on in a game but we were definitely a bit loose and it was not the start we wanted.
"We responded well but you don't want to go seven points down in a knockout game so early on.
"I still had a job to do when I came on and you can never say that a game is won.
"You want to help the team keep it going through the game and into the final."
