Italy coach John Kirwan has made just the one change for the Azzurri's crunch Pool D game against Canada on Tuesday.
Mirco Bergamasco is selected on the wing for Nicola Mazzucato who will be rested.
"Canada are much stronger than Tonga, but they have a similar style of play," Kirwan said. "This has always been our major game as far as we are concerned."
Kirwan said he was impressed with the manner in which Canada competed against the All Blacks yesterday.
