Italy goalkeeper Federico Marchetti is determined to prove his worth against New Zealand on Sunday.
The 27-year-old came off the bench against Paraguay in the Azzurri's opening World Cup game after regular No.1 Gianluigi Buffon suffered a herniated disc.
Marchetti, who plays for Serie A outfit Cagliari, hopes he can put in a good performance against the All Whites as Italy look to progress from Group F.
"I am convinced I can play a good game on Sunday," he said.
"The other night against Paraguay, I knew that Gigi (Buffon) had a problem and hence I was mentally ready to replace him."
Buffon has been a mainstay between the sticks for Italy over the last 13 years and his absence will be a blow for the Azzurri.
The 32-year-old hopes to be fit for the final, should Marcello Lippi's men reach that stage.
Marchetti says he has the backing of Buffon, but insists he is a different type of keeper compared to the Juventus man.
"Buffon and I are different," he added. "He is faster and more reactive. I am more muscular and explosive.
"I believe to have courage and awareness of your talent are the basis to have success.
"I feel the confidence of my team-mates. Buffon just told me to show what I'm capable of doing. He trusts me.
"I plan to enjoy Sunday's game, I am calm and ready to help the national team."
