The Samoans stunned the favourites with three first-half tries to take a three-point lead at the interval, but Laidlaw’s boot proved the difference between the two teams.

The scrum-half kicked 26 of Scotland’s points and fittingly crossed for the 74th minute try which effectively sealed a last-eight place for Vern Cotter’s men.

Scotland continued to push for another crucial score and, after a period of ferocious pressure, WP Nel almost barged over but was denied following a video review.

Finally and fittingly it was Laidlaw who squirmed free to cross and surely book his team’s place in the World Cup quarter-finals.

However, there was still time for one last scare for the Scots when replacement Motu Matu’u crossed with two minutes to go as the Samoans reduced the deficit to three points.
