England coach Eddie Jones believes his team suffered in the Rugby World Cup final, because they received too much praise for beating the All Blacks in the semis.
After England destroyed New Zealand 19-7, Jones' side capitulated in the World Cup final a week later, falling 32-12 to South Africa.
Writing in his soon-to-be-released autobiography My Life and Rugby, Jones said his team's mindset wasn't right heading into the final, because they failed to stay grounded after beating the All Blacks.
"There's also a psychological challenge after the kind of big win we achieved against the All Blacks," Jones said in his autobiography, as reported by The Times.
"While we did play well, I thought the analysis was a bit over the top. Everyone was slapping us on the back, saying how fantastic we were, how it was the best-ever performance by an England team and the best-ever win at a World Cup.
"The praise was everywhere - the challenge is to bring the players back to reality. It changes the structure and narrative of the week."
England were chasing their second World Cup title, after previously winning it in 2003.
Jones' book is released on November 21.
