Young Walsall keeper David Grof hopes to keep his place after impressing while standing in for Jimmy Walker at Huddersfield last weekend.
The 22-year-old from Budapest made several terrific saves during the 1-1 draw against the Terriers.
"I came in and I just did my job. It's down to the gaffer if he's going to pick me for next Saturday or not," Grof told BBC WM.
"It's just one game. I've played before so the gaffer knows what I can do."
Saddlers boss Dean Smith will have a decision to make for the FA Cup first round tie at Exeter, as Walker, 38, has now served his one-match suspension after being sent off against MK Dons.
And Grof seemingly relishes the friendly rivalry with the keeper who has played 519 competitive games for Walsall.
"Jimmy and I are really close. He knows what I can do as well and he's looking after me on and off the pitch," said the Hungarian. "I'm happy if he's doing well and he's happy if I'm doing well.
"We're really good friends by now, but I've got my chance and I hope I took it."
Grof grew up watching English football and was particularly taken by the FA Cup, leaving him eager to make his debut in the oldest knockout competition in the world.
"If I get to play I'd be really happy. I don't think I've ever played an FA Cup game before," he said.
"My dream team is Manchester United so it'd be great if we could get them and maybe go to Old Trafford."
