Wales coach Warren Gatland has suggested that rivals England are an unsettled unit, unlike his own side.
The 51-year-old believes that England coach Stuart Lancaster faces a number of difficult decisions regarding his Rugby World Cup squad, while Wales are more comfortable going into the tournament.
Speaking to reporters after naming his 31-man squad, Gatland said: "Who are [England] going to play at nine and 10? Who are they going to play in midfield? What is the make-up of their back-row? They need [Geoff] Parling to call their lineouts - who is his partner and who comes off the bench?
"We are a little bit more settled and more comfortable with the experience and combinations that we've got.
"Obviously they have got some world-class players and the depth that I would love to have, but they are not 100% sure of where they are going."
England will take on Wales at the World Cup on Saturday, September 26.
