Exeter Chiefs fly-half Gareth Steenson wants to use Saturday's Amlin Challenge Cup match at Cavalieri Prato to show his coaches what he is capable of.
The 27-year-old was a regular last season but has lost his place to Argentina international Ignacio Mieres.
"There's no point in saying it's not frustrating but the team's been going really well," Steenson said.
"You've got to take your opportunities whenever they come and hopefully there's an one for me this weekend."
He added: "It's an opportunity for myself, but it's also an opportunity for a lot of the guys who are getting a start this weekend."
A victory for Exeter would ensure they stay top of their group going into their final match at home to Perpignan next week.
"It's quite exciting, it's obviously going to be a tough game out there, it's an away European fixture so it's certainly not going to be easy," he told BBC Radio Devon.
"I think for a lot of guys its an opportunity to put their hands up and maybe say 'we're still here'."
