NBA superstar James Harden has said the Philadelphia 76ers have all the pieces in place to challenge for an NBA championship after signing a new deal to remain with the franchise Wednesday.

U.S. media reported last week that the 10-time All-Star had agreed to a restructured two-year deal worth $68.6 million in a move that helps the Sixers bolster their roster.

The Sixers did not release terms of Harden's new deal in a statement confirming his resigning Wednesday.

Harden, who joined the Sixers in February in a blockbuster trade with the Brooklyn Nets, expressed delight at the deal.

"This is where I want to be. This is where I want to win, and I think we have the pieces to accomplish that goal," Harden said.

"From my first day with the 76ers organization, the team and the fans have helped me feel at home here in Philadelphia.

"I'm excited to build off of last season and I can't wait to get out on the court with the guys and start this journey."

Harden scored 442 points, 149 rebounds and 220 assists in his 21 games with the 76ers last season.

Sixers coach Doc Rivers welcomed Harden's decision to pledge his future to the team.

"I couldn't be happier with James' decision to commit to our organization," Rivers said.

"Over the last two years we have taken major steps toward our ultimate goal of becoming champions. James shares our drive to win a title, and he believes being a 76er gives him the best opportunity to do that."

Reports have said Harden will make $33 million in the 2022-23 season in the deal that also includes a $35.6 million player option for 2023-24.

He declined his $47.4 million player option for the coming season to help the Sixers strengthen their roster.
