"He can't force his way into the team, but I've never seen in recent times as many match-winners across the park - guys like George North, [Alex] Cuthbert, Jamie Roberts, Warburton, [Toby] Faletau in the back row, Gethin Jenkins coming back in [at prop].

"We're not just dependent on one or two players to do something special for us.

"We've got them right across the park now so I think we're looking as dangerous as we ever have.”
