New Scotland coach Andy Robinson believes his A squad will have to step up their performance a couple of gears if they are to defeat France A on Sunday.
The former England coach has made an encouraging start to his reign as Scotland coach with two consecutive wins in the IRB Nations Cup in Romania.
The A side defeated Russia convincingly in the tournament's opening game before a more laboured victory against Uruguay.
The Scots sit top of the table with the winner-takes-all match against France's second string still to come.
Scotland have taken a very strong squad to Romania with effectively a full team of capped internationals, some of whom played in the 2009 RBS 6 Nations.
But Robinson feels their performances will have to improve if they are to trouble France this weekend.
He said: “The players have worked extremely hard so it is really pleasing to see all that work translate into the fact we are at the top of the table.
“But there are still plenty of improvements that need to be made between now and our final match.
“France A have a number of quality players and collectively the players know they must raise their level of performance for what will be a really tough challenge.
“Over the first two games, we have highlighted the positives but, more importantly, addressed the mistakes in order to improve every player’s game understanding.”
