England strive to be sharper

London - Stuart Lancaster admits his England players simply must be more clinical and ruthless against France if they are to capture the Six Nations title at Twickenham.

The head coach was left with mixed emotions after the 25-13 victory over Scotland which was much more of a struggle than it needed to be with the hosts blowing hot and cold in front of the try line.

Jack Nowell's late try, England's third of the game, ensured Lancaster's team jumped to the Six Nations summit. But only just.
