Scotland will target a first victory in Cardiff for 20 years on Saturday when they tackle Guinness Six Nations opponents Wales

And two of the key performers are likely to be flankers Taine Basham and Hamish Watson.

Basham, who has been switched to blindside for the clash, and openside Watson will be ones to watch as the opposing packs battle for supremacy.

Here, the PA news agency assesses an intriguing contest.

Taine Basham – Dragons

Position: Flanker

Age: 22

Caps: 8

Debut: versus Canada, 2021

Height: 6′ 0″

Weight: 14st 11lbs

Points: 15 (three tries)

It is not stretching the point to claim that Basham has been the find of Wayne Pivac’s Wales coaching reign. The Dragons flanker only made his Test debut last summer, but he shone against southern hemisphere heavyweights New Zealand, South Africa and Australia earlier this season, then in adversity against Ireland last weekend he scored a try and was top of Wales’ charts in terms of carries, metres made and tackles made. At just 22, he is currently one of the first names on Pivac’s team-sheet, having served his apprenticeship at Talywain and Cross Keys rugby clubs before entering full-time professional rugby. He looks to have a long international career ahead of him.

Hamish Watson – Edinburgh

Position: Flanker

Age: 30

Caps: 46

Debut: versus Italy, 2015

Height: 6′ 1″

Weight: 15st 3lbs

Points: 30 (six tries)

Edinburgh forward Watson has proved an integral part of Scotland’s renaissance under head coach Gregor Townsend. A consistently-impressive contributor, his pace, outstanding work at the breakdown and relentless tackle-count make him one of the most dynamic back-row operators around. He became only the second Scotsman after current captain Stuart Hogg to be named Six Nations player of the tournament when he won that accolade last season, and then he gained selection for the British and Irish Lions’ South Africa tour, featuring off the bench in their third Test defeat. Scotland are shaping up as serious Six Nations title contenders as the countdown continues to next year’s World Cup in France, with Watson firmly established among Townsend’s on-pitch lieutenants.
