Argentina had too much pace, power and guile for Wales, whose defence was again desperate but sometimes lacking in first-up tackling.

“There’s a lot of lessons in there for us,” said Tandy.

“Coming away from home we need to be a bit more accurate and Argentina probably dominated the physicality.

“It’s something we definitely need to look at. We fell off a few tackles in the first half and that creates momentum which is hard to wrestle back.”

A quick look at the match stats again demonstrate how dominant Wales’ opponents were at times.

Argentina made 458 metres in attack, with 15 clean breaks and 31 defenders beaten compared to Wales managing just 209 metres, three clean breaks and 15 defenders beaten.

Wales’ attack is more methodical with their three tries scored by front-row forwards Dewi Lake, Ben Warren and Rhys Carre – who scored for the fifth time in six internationals with a well-worked try.

Getting over the gain line was a major issue for Wales in San Juan and the offensive game against the Pumas was more pedestrian than their opponents.

The jury is still out on the Wales midfield with Scarlets trio Sam Costelow, Joe Hawkins and Eddie James chosen this weekend.

Wales’ main threat comes from the driving line-out and it was only in the final quarter that the attack threatened to demonstrate any fluidity.

Wales flanker Jac Morgan was again the pick of the bunch in San Juan with 23 tackles, impressive turnover and one second-half burst highlighting his all-round influence.

Exeter back-rower Kane James was prominent as a second-half replacement winning his first cap.
