Warren Gatland has made four personnel changes to face South Africa this weekend, with Sam Costelow starting and Blair Murray moving to full-back for the final match of Wales' autumn campaign.

The visit of Rassie Erasmus' back-to-back world champions to Cardiff could spell the end of Gatland's second spell in charge of Wales as pressure builds following 11 straight defeats at Test level.

Questions still remain over the head coach's future, with speculation rife after he questioned his own position after the defeat to Australia on Sunday. You can follow Gatland's press conference today live here now.

However, as Wales bid to spring an upset that would see them avoid a first winless calendar year since 1937, Gatland has opted to make changes.

Costelow is handed a start in the fly-half jersey, replacing Gareth Anscombe, while Rio Dyer comes in for his first appearance of the autumn.

He takes up Murray's place on the wing, with the Scarlets man moving to full-back to replace Cameron Winnett in what will be his first start at 15 in a professional game.

Without fly-half Anscombe, the starting backline boasts just 61 caps, while the entire matchday squad has just 334 caps. For context, there's 431 caps alone on South Africa's bench.

In the pack, Taine Plumtree comes back into the side, taking Aaron Wainwright's No. 8 jersey, while Christ Tshiunza replaces the injured Adam Beard.

On the bench, Gloucester lock Freddie Thomas is in line for a Test debut, while his club team-mate Josh Hathaway is set for a first appearance of the autumn.

“Last week’s result hurts and we are just as disappointed by it as the fans," said Gatland. "Our focus now is on training and preparing well for our final game of this Autumn Nations Series.

“There were good elements that we can definitely build on going into Saturday but we have to improve our accuracy.

“We know what a quality side South Africa are and the physicality they bring. This week we need to show real courage and front up against the World Champions.”

Wales: Blair Murray; Tom Rogers, Max Llewellyn, Ben Thomas, Rio Dyer; Sam Costelow, Ellis Bevan; Gareth Thomas, Dewi Lake (c), Archie Griffin, Will Rowlands, Christ Tshiunza, James Botham, Jac Morgan, Taine Plumtree.
