Wales head coach Warren Gatland has said his side are far more settled in terms of selection than World Cup Pool A rival England.
Gatland, speaking after the announcement of Wales' squad for the tournament, believes that his counterpart Stuart Lancaster has a lot of questions remaining when it comes down to who he should select in certain positions.
"We are much more settled," Gatland told reporters.
"England have got the problem of which way they want to play and who they want to play.
"Who are they 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 (England) have got some world-class players and the depth that I would love to have, but they are not 100 per cent sure of where they are going."
Despite England's supposed areas of uncertainty, Gatland admitted that there was very little between the two sides and that picking a winner was no easy task.
"It's a toss of a coin, isn't it?
"There's a bit of respect between the two teams, and on the day we are both capable of beating each other.
"As a coach, I've had some great success at Twickenham. I think it's a great stadium and I love going there. It's been lucky for me, and may it continue to be so."
