England's rugby coach Chris Robshaw reacted to their spirited loss to the All Blacks at Twickenham by declaring that his side must win a Six Nations title to provide evidence of genuine progress.
The All Blacks avenged last year's loss in London with a 30-22 victory, but they were made to look far from invulnerable.
It was the only loss for England in their last in 11 matches, but Robshaw insists any loss - even to the World Cup holders in a breathless test - is unacceptable.
England tour here in June, playing three tests and one midweek game, and the teams will lock horns once again next autumn.
Meanwhile England's New Zealand-born hooker Dylan Hartley, who needed hospital treatment after suffering bruising to a lung, has been discharged.
