Australian speedster Mack Hansen says his Irish team may need to “rough up” Ange Capuozzo to help prevent Italy’s “super-quick whippets” from derailing their quest for grand-slam glory.

Andy Farrell’s men go into Saturday’s tricky trip to Rome sitting in pole position for the Six Nations title on the back of bonus-point wins over Wales and France.

The resurgent Azzurri snapped a 36-match losing streak in the championship by defeating the Welsh in 2022, and they backed up that shock result with a historic success over Australia.

Hansen, the Australian winger who qualifies for Ireland through his Cork-born mother, is wary of “genuine superstars” in the opposing ranks.

And the man from Canberra feels Toulouse fullback Capuozzo, who created his country’s winning score in Cardiff, before claiming two tries against the Wallabies in the autumn, requires special attention.

“He’s an eyes-up player, so I think if we can get our hands on him and rough him up a bit, that would help us,” he said of 23-year-old Capuozzo. “He’s not the world’s biggest player, but he’s so quick that we’re probably going to have to hunt in threes to take care of him.

“But, when it comes to it, we’re going to have to focus on every player in that backline as well – they’re all super-quick whippets.

“I’ve done a little bit of footage on him. He’ll be dangerous but we’re ready for him.”

Capuozzo also was on the scoresheet as Italy continued its improvement by giving Six Nations champion, France, a major scare during a 29-24 defeat at the start of this year’s tournament.

Hansen feels the Azzurri, who lost 31-14 to England in Round 2, never have been stronger.

“Anyone would be kidding themselves if they said they’ve seen a better one,” the Connacht player said of Italy’s team. “They got a great win in Wales, and against Oz. They genuinely have some genuine superstars on their team now who are carrying it. They’re not just good, solid Italian players. They’re actually world-class players.”

Hansen is in line for his third successive start of the competition at Stadio Olimpico, but he still is searching for his first try.

The 24-year-old looked certain to score in Ireland’s 32-19 win over Les Bleus in Round 2, before somehow being hauled off the try-line and into touch by the brilliance of Antoine Dupont.

“It just showed his brute strength, first of all, but it also just shows how smart of a player he is,” Hansen said of France’s captain. “I’ve seen plenty of people in the same situation, where they just try to tackle a player out, and that’s kind of it.

“I’ve never seen anybody go directly for someone’s hips to lift them up so they can’t go forward.

“I don’t know what else I could have done. If I was in that situation again, maybe I’ll just dive or jump in the air or something like that, something a bit different but it was some play from him.”
