South Africa v Wales: Welsh will improve - Dan Biggar

Dan Biggar of Wales watches his drop goal go through the posts

Wales will "roll their sleeves up" in Nelspruit on Saturday in a bid to avenge their opening Test defeat to South Africa, says fly-half Dan Biggar.

Wales go into the second Test knowing they have a mountain to climb after coming out very much second best in the 38-16 defeat to the Springboks.

"Do we give in this week and say we'll make up the numbers up?" said Biggar.

"Or do we roll our sleeves up and go out and really show how tough we are and go and compete?"

He added: "That's the mental attitude we have got this week."

The Ospreys half-back admitted the Wales camp were "gutted" they did not give a good account of themselves at Kings Park in Durban.

"As good a side as they are, we felt we gave them quite a few cheap points, and against a side like South Africa... they are going to capitalise on any sort of mistakes you make," he said.

"We are gutted. We are disappointed as a group."

But as down as Wales were on Saturday night, they realised they came up against a crack Springboks unit with Biggar paying particular credit to full-back Willie le Roux and the South African back-row.

"He [le Roux] was outstanding and deserved all the plaudits he gets," reflected 24-year-old Biggar, who won his 24th cap last weekend, kicking 11 points, including two drop-goals.

"From our point of view, it's about looking forward now and try to make life as uncomfortable for him as possible.

"We know what a threat he is and if we can nullify as many opportunities as he gets, then I think we might do a decent job of maybe winning the game and challenging South Africa a little bit more.

"The South African back-row were outstanding. It's pretty difficult to shift them.

"Understandably we know how tough it's going to be, but we are going to give it a good go and be as positive as we can on Saturday."

Wales coach Warren Gatland is set to name his team on Thursday and there could be a few changes.

Scrum-half Gareth Davies and utility back Matthew Morgan caught the eye after making their debuts off the bench.

And veteran tight-head prop Adam Jones, playing in his 100th Test, was replaced in the 31st minute by Samson Lee, 21, who was making his fourth appearance.
