England’s Captain Chris Robshaw blamed England’s “shocking” first-half discipline for their 25-20 defeat by France in Paris.
Head coach Stuart Lancaster’s World Cup preparations suffered a blow as for the first 70 minutes a largely first-choice XV struggled to deal with French power.
Two late tries flattered the visitors, who have one game left before launching their World Cup campaign against Fiji on 18 September.
“We gave away penalties and our discipline was shocking,” said Robshaw.
“Whether it was rust, or nerves, it wasn’t good enough. Credit to France, they put us under pressure and made us make mistakes.
“We gave too many penalties away, but in the second half we came out and played well but couldn’t quite get over the line in the end,” he told Sky Sports. “We can’t give teams like France and other quality sides head starts like we did.
“We’ll look long and hard at ourselves, because we let ourselves down in the first half. We played well in phases but you can’t wait for 40 minutes to do that.”
