Chris Robshaw has claimed that Italy's underdogs tag makes them a big threat ahead of Saturday's meeting between the two sides in the Six Nations.

Stuart Lancaster's men are firm favourites to add another win to last week's triumph over Wales, but Robshaw believes that Italy can play with freedom at Twickenham.

"It'll be a completely different pressure compared to Wales," Robshaw is quoted as saying by Sky Sports News. "I'm sure most people will be coming to Twickenham expecting us to win comfortably, but we know what we've got to do and the aims we set for ourselves.

"You want to perform well and you also want to win. You hope as a team you'll be more cohesive and it's that different type of pressure.

"They're away from home and are the underdogs. There's not really anything to lose. When you're the favourites, so to speak, it is a different type of pressure."

Italy started their campaign with a 26-3 defeat to Ireland last Saturday.
