Australia fly-half Berrick Barnes insists the pressure is on Danny Cipriani to prove he can cope with life on the international stage.
Barnes misses the chance of a Twickenham showdown with England star Cipriani after he damaged his knee ligaments against Italy on Saturday.
However, Barnes believes that his replacement in the Wallabies No.10 jersey Matt Giteau and New Zealand's Dan Carter will test Cipriani's credentials.
The 22-year-old, who faces around six weeks on the sidelines, said: "One of his hardest things is that he has a lot of pressure on him.
"Everyone is looking to him as the next big thing. He carries himself pretty confidently. It will be interesting to see him go up against Gits this weekend.
"He will come up against some really good 10s in the next couple of weeks - Matt Giteau and (New Zealand's) Dan Carter. They will give him an indication, and everyone else, where he is.
"He is obviously a talent. He is a young guy with a lot of weight on his shoulders but he has an opportunity now to set himself up for the next 10 years.
"I think it is amazing how he has come back off his broken leg as well."
