Rugby league star Sam Burgess has defended his brief foray into rugby union, saying egos and selfishness derailed England's 2015 World Cup campaign, not his presence.

Burgess was a high-profile recruit for England ahead of the tournament and shouldered much of the blame when Stuart Lancaster's men became the first host nation to exit in the group stages.

Critics said the league convert's fast-track into international rugby disrupted team unity, while supporters said he was a convenient scapegoat for England's many failings.

Burgess, who returned to the 13-a-side code with South Sydney Rabbitohs soon after England's elimination, was silent on the issue until this week, when he responded to goading on social media.

I seem to be getting a few tweets regarding the Rugby WC in 2015....Still. If people actually rewatched the games I participated in You will see I added to the team. What cost us an early exit was individual egos and selfish players not following our leader. Which ....

Essentially cost the coach and other great men their jobs. Tournaments are not won by the coaching staff or one player. It takes a commitment from the full group. I guarantee you this, I was committed but others had their own agendas. I have fond memories of my time in RU

"If people actually re-watched the games I participated in, you will see I added to the team," he tweeted. 

"What cost us an early exit was individual egos and selfish players not following our leader, which essentially cost the coach and other great men their jobs."

Lancaster and his assistants -- including defense guru Andy Farrell, who is set to take over as Ireland coach next year -- were sacked after the 2015 failure.

But Burgess said they were let down by some members of the England playing group, who he did not name.

"Tournaments are not won by the coaching staff or one player," he said. "It takes a commitment from the full group. I guarantee you this, I was committed but others had their own agendas."

He added "one day I will tell my side of the story", saying he had enjoyed his time in rugby union and was looking forward to watching England at next year's World Cup in Japan.
