Hastoy has made 13 European Rugby Challenge Cup appearances for Pau, racking up 35 points in the process.

He is one of seven changes made by France head coach Fabien Galthie to the starting XV for the final Test, having seen his side beaten in the opening Test in Brisbane on July 7, before picking up a 28-26 win in Melbourne three days ago.

Full-back Melvyn Jaminet, who will likely feature for USAP in the Challenge Cup next campaign, slotted seven penalties to help France to victory on Tuesday and retains his place in the back three.

Arthur Vincent and Enzo Forletta, who both played in Montpellier Hérault Rugby’s Challenge Cup final triumph over Leicester Tigers back in May, start at centre and prop respectively.

Vincent is partnered at centre by Lyon’s Pierre-Louis Barassi, whose clubmates Baptiste Couilloud and Dylan Cretin also make Les Bleus’ starting team.

Wales have also made seven changes to the side who were held to a 20-20 draw against Argentina last week for Saturday’s decider against the Pumas in Cardiff, with Cardiff Rugby duo Jarrod Evans and Tomos Williams forming the half-back combination.

Saracens’ Nick Tompkins starts at centre, with Dragons quartet Elliot Dee, Leon Brown, Ben Carter and Ross Moriarty all part of the pack.

Scarlets centre Jonathan Davies has been deemed fit to play and will captain the side at the Principality Stadium.

Section Paloise fly-half Antoine Hastoy is set gain his first cap for France in their series-deciding Test match against Australia on Saturday.
