Ben Youngs backs 'rough diamond' Ellis Genge to lead England

England's most-capped player, Ben Youngs, has backed former "rough diamond" Ellis Genge to lead the side in their November international opener against Argentina at Twickenham.

Youngs, 33, added: "When you're blessed with that power and aggression you've still got to work out how to use it effectively and he's done that. 

"The Ellis that turned up at Tigers compared to the one that's here today are very different characters.
