The Harlequins half-back has played a role off the bench for much of the competition but has helped England maintain a winning run this year following encounters with Scotland, Ireland and France.
England are now preparing to host Italy at Twickenham next weekend, whilst the Welsh make the trip to Murrayfield to face a Scotland side who beat Ireland 12-8 in their last outing.
A win for both England and Wales in the penultimate round of fixtures would set up a mouth-watering showdown at the Millennium Stadium later this month.
However. Care has insisted the squad are looking to take it one game at a time, as they continue preparations for the Azzurri.
He said: "We have a week without an international now so we can get our review of the France game done and we can see what we did well, see what we need to improve.
"It is all about Italy now. We can't think about the Wales game."
