Former Wales back-row Martyn Williams is confident Taulupe Faletau can play on the blindside for the British and Irish Lions on their tour.
Faletau scored a hat-trick for club side Bath on Sunday as they beat Gloucester 44-20, playing in his usual number eight role at the Rec.
And his form clearly impressed Williams, who believes the Welsh international could easily switch to the six shirt under Warren Gatland.
"Some people questioned him being selected which is ridiculous," he told BBC Wales' Scrum V programme.
"He's world class and it goes to show how well Ross Moriarty, Justin Tipuric and Sam Warburton were playing to keep him out of the Wales team.
"I wouldn't be surprised if he ends up playing at six and Vunipola at eight and then Warburton at seven.
"I think that's something Gatland would look at.
"He's got all the skills Taulupe, and it's a real bonus for the Lions that he's fit and firing."
