Scotland head coach Vern Cotter last night praised his players for marking his first home game with a victory, but the New Zealander admitted that some things will have to tighten up before his side face his own countrymen at BT Murrayfield next weekend.

The fact the Scots leaked three tries in the final 10 minutes against Argentina was an obvious cause for concern, but Cotter suggested they might not have been given a fair crack of the whip by referee Wayne Barnes during that period, although he refused to elaborate before he had a chance to watch the replay of the match.

"I really enjoyed watching the players play for each other," Cotter said. "Several times when we were a man down with yellow cards, I saw players get up off the ground and help their team-mates. And, of course, to score five tries was great as well. We varied our play well which was good, too.

"But there are things to work on. We are certainly not getting carried away. We are playing the best team in the world next week. We will be looking at where we conceded penalties and I'm sure there will be a lot of player input as well."

Cotter reported that there were no significant injuries, although he did confirm that a number of players will have to be checked out by the team medics before they are cleared to resume training early this week.

Henry Pyrgos took a knock to his head in the closing stages, and seems to be the most obvious doubt for the game against the All Blacks. Cotter admitted that the opening minutes of yesterday's match, during which Argentina flanker Javier Desio claimed a try after just 90 seconds, had been unsettling, but he paid credit to his players for their ability to strike back quickly.

Cotter said: "It was a tough way to start. We had the ball and were looking dangerous but got turned over and that finished with a try against the run of play.

"But what was really pleasing was that we turned around and scored so quickly."

Scotland captain and scrum-half Greig Laidlaw revealed that his man-of-the-match performance had been due to the rejuvenating effect of his close-season move from Edinburgh to Gloucester.

"I've got the spring back in my step after going down to Gloucester," Laidlaw said. "There is strong competition down there and you get the feeling playing [in] the Aviva Premiership that you have to win games week in, week out.

"Playing in pressure games has helped me, as has just moving to a new club where you have to prove yourself again.

"That has certainly brought my game on. Coming back up, I also knew that [rival scrum-halves] Henry Pyrgos and Chris Cusiter are playing well so I had to be on my toes."

Winger Tommy Seymour, who scored the last of the Scots' five tries, admitted that defensive errors near the end had been a disappointing way to finish the match, but added that he was generally happy with the way the team played.

Seymour said: "I wouldn't say the gloss was taken off because it was a very good performance, but there will be a measured review.

"We allowed our opponents to get scores on the board late on and get back in the game.

"If we had allowed those mistakes and lapses in concentration to happen earlier in the game then that margin could have been reduced."
