Former England coach Brian Ashton outlines the key questions of the Rugby World Cup in the Independent.
"Questions raised by the first weekend of World Cup action? There were many, but here are the ones I consider most significant:
1 The ball and the kickers. At what stage will the latter exert a satisfactory degree of control over the former?
2 How influential will the out-and-out open-side flankers be over the course of the tournament?
3 The physicality levels are already sky-high. This is bound to take its toll come the later stages of the competition, and when it does, will it open the gate for the high-tempo teams and their match-winning runners?"
