Farrell said: “It would have to be Jonny (Wilkinson), simple as that.
“The consistency he showed throughout his career was incredible, he set a new standard for fly-halves all over the world.
“Dan Carter is another one who has been incredible over a long period, but I’d have to stick with Jonny as my toughest opponent.”
DID YOU KNOW? He gained a place at the University of Durham, but gave his place up in 1997 to become a professional rugby union player with the Newcastle Falcons
