And there has been some early news this morning to set Welsh nerves trembling....
Jonathan Davies. midfield keystone and defensive captain, has been ruled out of the match after aggravating a knee injury that he first picked up against Fiji.
Owen Watkin comes into the centres with Leigh Halfpenny promoted to the bench.
There has been no indication yet from the WRU whether Davies will be ruled out for the rest of the tournament should Wales defeat France in the last eight.
