France centre Damien Traille has admitted he was frustrated by his side's mistakes even though they thrashed Scotland 38-3.
Four tries and a solid kicking game did not hide the fact that France have room for improvement in some important areas if they want to keep their title hopes alive when they face high-flyers Ireland on March 8.
"The success is a big one," said Traille, who scored France's third try.
"But we are frustrated because we lost a lot of ball mainly due to the fact that we rushed things.
"We wanted to make the most of the spaces because we knew that the Scottish players usually get disorganised after a while.
"The positive thing is that we did not concede one single try," Traille added. "We worked hard on defence last week again and it paid off."
England Under-18 head coach John Fletcher insists his young side will be better for the experience after beating Italy in the bronze final to round out their 2015 Rugby Europe U18 Championship campaign in style.
