The game is certain to be one of the biggest ever to be staged on Wearside and Marton Fulop is confident he can better Darren Ward's performances to become first-choice.
Fulop said: "If I play tomorrow, I need to make the most of it.
"I'm ambitious. My aim this season is to play for Sunderland in the Premier League and to be the number one goalkeeper for Hungary.
"I want to show everyone in training and in matches that I'm good enough to be the first-choice goalkeeper at Sunderland."
Despite wanting nothing more than to keep a clean-sheet tomorrow, Fulop insists Juventus are one of his favourite teams.
"Juve are very popular in Hungary and they are one of my favourite teams.
"Some of their players in the past have been unbelievable and I have great resepect for [Gianluigi] Buffon [Juventus 'keeper].
"Juventus will be a great game. We will respect them but we don't fear them. We want to win."
