Wallace toured South Africa with Williams on the British Lions tour last summer and saw first-hand the qualities of the Cardiff Blues star, who has been named skipper in place of Ryan Jones.

Williams replaced Wallace for the third test win against the World Champions but the Ireland No.7 can’t wait to go toe-to-toe this time around.

“Martyn is a very good footballer. He’s very good at poaching the ball,” said Wallace. “If you don’t have good numbers around rucks, you leave yourself open for him to pilfer the ball.

“He can play like an outside-half or a winger at times – he has soft hands and can kick too and it’s hard to pick faults in his game.

“I’ve also done two tours with him – he’s a good leader and the guys will want to play for him.”
