In the latest episode of his Facebook video series Kickin It, the All Blacks great discussed World Cup losses with England star lock Maro Itoje, who was part of the side that dominated New Zealand in last year's semifinal in Japan but would go on to lose in the final to the Springboks.

Carter advised the 25-year-old Itoje to make sure he learned from the pain of the defeat, something the former first-five said he regrets he didn't do.

After losing to the Wallabies in his first World Cup in 2003, Carter said he quickly got over it and failed to take the lessons from that defeat, which he says contributed to the All Blacks' quarter-final shock loss to France in the next tournament.

"In a funny way, I'm glad that Maro is hurting a little bit because my first World Cup in 2003 I got over in four or five days," Carter said.

"Then I had a lot of success after that and got to 2007 and wasn't hurting as much as I should have from 2003.

"We got dealt with by the French in the quarterfinals and that one really hurt for a good six months.

"Through that hurt, you do digest what went wrong as a team and admitted we weren't a good team when it came to pressure. I'm not saying England were the same as us but there has to be something in there that they will learn from and become stronger."

Carter said he finally learned to build upon the disappointment of the 2007 World Cup, which ultimately helped towards the All Blacks' back-to-back triumphs in 2011 and 2015.

"We learnt from 2007 and that was the platform for us to be successful in 2011 and 2015.

"England now have a lot of guys who have experience and know what it took to get all the way to the final but not quite get there and that will hurt. It will feed their hunger come four years' time."

Itoje, who was one of the best players in last year's tournament, said he only recently watched the replay of England's loss to South Africa in the final, admitting that it is "still painful to watch".

"The final was extremely disappointing and it took me a long while to be able to watch the final. It was too painful," Itoje said to Carter.

"The first time I watched it back was during the lockdown and I wanted to take lessons from it. There are always lessons in victory and defeat and allowing my emotions to watch the game will make me a better player.

"It was still painful to watch, but I'm more optimistic about the future than the past and we have a lot of good years left in us."
