The 19-year-old defender may have the responsibility of marking the young Santos star, and has warned that he will tolerate no funny business in Thursday's Libertadores clash
The Argentines host Santos in the first leg of their Copa Libertadores quarter-final, having seen off the challenge of Colombian giants Atletico Nacional to make the last eight.
The Peixe, meanwhile, were inspired by a virtuoso Neymar performance as they crushed Bolivar 8-0 to continue their progress in the competition.
Peruzzi looks set to mark the 20-year-old striker as he gets the chance to start due to several absences in the Fortin side, and he has promised that he will not be intimidated by his more illustrious adversary.
"I know Neymar has no idea who I am, but he will get to know me soon enough," the 19-year-old laughed in Wednesday's interview with Ole.
"I would tell him to watch his back. I am a player who hits hard and who has a lot of character. I give everything on the pitch."
Asked what he would do if Neymar pulled out his famous bicicleta overhead flick, the defender gave an unequivocal response.
"If I grab him afterwards, I'll break him in half! No, it's true that it is annoying when he does these things while winning but he always plays like this. He likes the tricks," he admitted.
"I have to keep cool; the Brazilians love to show off and I'm a bit of a hothead!"
And to put further distance between himself and the Barcelona and Real Madrid target, Peruzzi vowed that fans will never see him mark a goal with a dance rendition of Ai se eu te pego, the recent South American hit.
"I only dance Cordobes cuarteto!"
