Nigel Owens ranks the three worst Six Nations stars to referee

Owens said: "He was always a funny one on the field in nice way. You'd be trying to tell him something serious and he'd just want to have a laugh and a joke. He'd wink at you on the middle of a serious telling off."

Owens said: “I’m not saying Peter O’Mahony is a dirty player one bit but he certainly has a bit of history. I remember seeing him square up to Sinckler and thinking I’m glad I haven’t ran into him in a dark alley. You can hear his loud voice bellow from a mile away.”

Owens said: "Oh god yes, Biggar can be a tricky customer on the field.

"He's so focused and so passionate about what he's doing no matter the game or occasion, we've had a few run ins on the pitch down the years.

"I mean, it's always been in a respectful way and we always have a drink and a laugh after the game."
