With the No.1 shirt up for grabs, Zanusso, who has featured in 12 of Treviso's 13 GUINNESS PRO12 contests this season, is keen to take the chance to shine.
"Going from the PRO12 to the Six Nations, the level of pressure and emotion is something else," he told Gazzetta dello Sport.
"Now I am concentrating on the work I have to do get up to speed as quickly as possible.
"Knowing that (he and Lovotti are the only two looseheads) gives you even more responsibility."
