Leigh Halfpenny has hailed Wales's "special" backline, and admits that he does not mind being the smallest player in it.

Halfpenny, who can play at fullback or wing, has been one of Wales's stand-out stars so far this Six Nations tournament, kicking the winning penalty during their 23-21 win over Ireland on opening weekend.

"It's comforting to be around such a big backline. They can protect me," Halfpenny said.

"I'm a bit smaller [than the rest]. It's been great to be part of such a special backline. We have got some awesome ball-carriers and they have got plenty of skills as well.

"We have been together for a while and we really gelling and are comfortable around each other and we are working well as a unit."

Wales will be chasing their 20th Triple Crown when they face England at Twickenham on Saturday.
