Scotland head coach Vern Cotter hailed the performance of his team's captain, Greig Laidlaw, during their 36-33 Pool B victory over Samoa in Newcastle on Saturday.
Laidlaw contributed 26 points via a try, three conversions and five penalties and his leadership helped Scotland fight back from a 26-23 deficit at half-time to clinch victory which secured them second spot in the pool and a quarter-final showdown with Australia at Twickenham next Sunday.
“Greig’s performance speaks for itself,” said Cotter.
“He had an outstanding game, no two ways about it.
"Everybody knows and acknowledges his qualities as a leader and as a player.”
Laidlaw expressed his delight at reaching the quarter-finals and believes they can cause an upset by beating the Wallabies.
“It’s a great feeling.” said Laidlaw.
“We’re absolutely delighted, especially after missing out (on a quarter-final place) four years ago. It’s a great day for Scottish rugby.
“There were times in the game when we were down but credit to Vern and the coaches. They calmed us down at half-time.
“It’s a great achievement, probably the greatest honour of my career. Our goal from the outset was to qualify for the quarter-finals and we’re not finished yet. We believe there’s more to come.
“We believe we’re a dangerous side. Sean Lamont just said in the dressing that in his 100 caps this is the best squad in feeling of camaraderie.
"That goes a long way and that showed today.
“We’ll enjoy tonight and we’ll go into the quarter-finals with confidence.”
