Chris Robshaw has credited the work done off the field by Harlequins boss Conor O'Shea to keep him fresh and upbeat ahead of the 'Big Game'.
Robshaw's future as England captain has been scrutinised ever since the team were knocked out of the Rugby World Cup.
Admitting that his confidence had taken a knock, the 29-year-old said there was no instant cure for getting over such a disastrous outcome for the host nation, but that there were signs that some of the World Cup squad were beginning to turn a corner.
"I've never been managed before as well as I have this year," Robshaw said.
"Conor has been incredible. He has taken good care of me, whether that's putting you on the bench, giving you a week off, making sure injuries are up to date.
"It's all been hugely important and I now feel in a very good place.
"Post-World Cup the first month was pretty tough. Myself, and probably most of the England boys, going back to your club, your confidence has been knocked a bit.
"The World Cup is still lingering in the back of your mind. You look at the guys in the last month compared to that initial month and the English guys have picked up steam, got it out of their systems and are playing tremendously well.
"You look at them, and they have a smile back on their faces. There is no magical cure, you need time."
