England Rugby Coach Eddie Jones says their conduct after victory over the All Blacks at the Rugby World Cup came back to haunt them in the final.

Jones says his side could not back up the performance against the All Blacks in their 32-12 loss to the Springboks in the final.

Writing in his new book My Life and Rugby Jones spoke about England's mindset leading into the final, saying that he got it wrong in keeping his side's feet on the ground after their victory over the All Blacks.

He says the analysis was a bit over the top as everyone was slapping them on the back, saying how fantastic they were and how it was the best ever performance by an England team at a World Cup.

Jones' book was released on the 2nd of this month.
