Frederick Michalak scored 13 points for France in their defeat against Australia
France fly-half Frederick Michalak admits his side made it too easy for Australia in their 50-23 first Test defeat in Brisbane on Saturday.
The Wallabies scored seven tries to France's two to keep intact their 24-year winning streak over the French on Australian soil.
And Michalak, who failed to play any part in the 2014 RBS 6 Nations, says it was a harsh lesson.
"It was very tough for us, we played a bad game," said Michalak, who scored 13 points with the boot.
"I think we didn't perform in defence, it was too easy for the Aussies tonight, and I hope next week we will be better in defence and be stronger.
"A couple of guys only arrived on Tuesday, it's not easy with the jetlag, but that's not an excuse. When you play for the French team you need to be 100 per cent and to play your best rugby, and tonight wasn't our best rugby.
"It's good for next week to see if we can beat them on the scrum, to build more phases and be more patient when we see the line.
"Tonight we were too stressed and couldn't finish our action."
England Under-20s may have agonisingly missed out on a third straight World Rugby U20 Championship title on Saturday but head coach Jon Callard is adamant that fans are witnessing the next generation of international superstars.
Italy Under-20s held off a late Samoa blitz to retain their place in the World Rugby U20 Championship on Saturday and head coach Alessandro Troncon believes the experience will have served as a valuable lesson for his young troops.
