“I’m proud of the effort because at 15-6 we’d given up a soft try straight after half-time, but we fought our way back in and put our nose in front.
“We can be a lot better. We had a lot of possession inside their 22, we didn’t convert and we knew Scotland were very good post-tackle and got their hand on the ball so we know we have to better against France.
“There’s been a hell of a lot of hard work from people so it’s pleasing to get a result."
