And Flood says England still have a lot to work on ahead of “Le Crunch” on Saturday, February 26.
“We don’t want to stay where we are,” said Flood. “Where do we want to be? I think we are content but certainly there are areas that we can improve on.
“There are large facets of the game where we kicked poorly or made a couple of poor decisions in our own half.
