England back-row Tom Wood admits his side have been left "kicking themselves" over their Round One Six Nations loss in Paris.
A sweeping late French move finished by replacement Gael Fickou broke English hearts in a match they had taken control of after conceding two early Yoann Huget tries.
And having won their remaining four fixtures, signing off with a 52-11 thumping of Italy in Rome, Wood and the squad know they effectively came within minutes of the title and a famous Grand Slam.
"We're really proud of the way we've performed and the results," Wood told PA Sport.
"We played some good rugby, a really good blend with attacking interplay between forwards and backs.
"We developed some more youngsters who have come into the side and done really well, so on the whole it's been a really successful campaign.
"We will look back and kick ourselves about that French result.
"If it hadn't been for the nervous start and bounces of the ball there, it could have been different at the end, but on the whole we've played really well."
England and Stuart Lancaster must now turn their attention to a June tour of New Zealand, a huge challenge made all the tougher for the fact that the Tests have been scheduled so close to the latter stages of the Premiership.
"New Zealand away is the ultimate test given the form they're in and their track record," admitted Wood.
"It will be a real test for us going out there on the back of a lot of the players being involved in the Premiership semi-finals and final."
