Stuart Lancaster's team became the first previous winners to go out in the pool stage after a 33-13 defeat by Australia at Twickenham on Saturday left them unable to reach the knockout stage.
Back-to-back losses against Wales and the Wallabies means England's final Pool A game against Uruguay on Saturday could be Lancaster's last game in charge with his future hanging in the balance.
England went into the tournament as second favourites but drawn in the toughest of the four groups, dubbed by Wales coach Warren Gatland as the "group of hell" because it included three of the top-ranked sides in the world.
When the draw was made in 2012, Wales had gone winless in their November 2012 tests and had dropped to ninth, Australia were third and England fifth.

By the time the tournament kicked off on Sept. 18, Australia were at two, England four and Wales five.
