James Harden believes he will combine well with Kevin Durant and Kyrie Irving at the Brooklyn Nets, talking up the "sacrifice" that would be required.

Harden, an eight-time All-Star, was traded from the Houston Rockets to the Nets in a move that was confirmed on Thursday.

Amid questions over how Harden will fit alongside Durant and Irving, the Nets recruit is confident – and said there would need to be sacrifices.

"Chemistry, sacrifice and like you said we're all elite so depending on the game, depending on what's going on throughout the course of the game, that's going to determine who gets the ball and who makes the plays," Harden told a news conference on Friday.

"We're all unselfish, we're all willing passers and we play basketball the right way and that's all that matters."

Asked what the Nets fans were getting, Harden said: "An elite player, an elite team-mate, an elite leader and just a guy that is willing to do whatever it takes to rack up as many wins as we can, sacrifice."

Harden's arrival enhances the Nets' championship hopes as the 31-year-old looks to win a maiden NBA title.

With Durant and Harden, the Nets now have two players who have won seven of the past 11 NBA scoring titles. No Brooklyn qualifier has ever finished higher than fifth.

Irving, Harden and Durant all rank in the top 10 in the NBA in scoring average (minimum 500 games) since the former's rookie season in 2011-12.

Harden said the Nets (7-6) were in position to contend.

"Obviously you've got Kevin Durant and Kyrie Irving on the team and then surrounded by those guys you have really good pieces in DeAndre [Jordan], Jeff [Green], shooters in Joe [Harris], Landry [Shamet]," he said.

"You just look at this entire roster and it's built for any style of basketball you want. And then the coaching staff who know the game of basketball at a high level.

"You just add that all together and that's a legit chance right there. It was a no-brainer for me."
