James Harden sees "unlimited possibilities" with the Los Angeles Clippers after making his debut for his new team.

Harden, who joined the Clippers last week in a blockbuster trade from the Philadelphia 76ers, had to wait until Monday to make his bow.

The 10-time All-Star played 31 minutes, finishing with 17 points and six assists, though he could not help the Clippers avoid a 111-97 defeat to the New York Knicks.

Harden is joining an elite lineup of experienced NBA stars at the Clippers, with Kawhi Leonard, Paul George and Russell Westbrook looking to propel the team towards success this season.

"Unlimited possibilities," Harden said when asked what he sees coming from his move to the Clippers.

It was not an easy debut for Harden, with the 34-year-old conceding it was tough to get up to speed having not had a full preseason following his fallout with the Sixers.

"I feel kind of weird out there, but just not really having a preseason game or an opportunity to participate in the full training camp or none of that," he added.

"It was just [being] out there and just basically winging it. Try to go off my basketball instincts and what I've been doing for the last few years or whatnot. I just went out there and playing and thinking the game and trying to make the game easier for everybody else."

Team-mate Leonard, though, was impressed with what he saw.

"He did a good job his first game in a while," Leonard said of Harden.

"It takes time to get his legs under him as far as conditioning. But he did a great job to me, got everybody involved running pick-and-roll very well."

The sentiment was echoed by Clippers coach Ty Lue, who said: "I thought overall just orchestrating, making the right play, making the right pass and pick-and-rolls, he was really good.

"It's going to take him a little time to get in game shape. We understand that, but his presence on the floor was definitely felt."

Harden is set to make his second Clippers appearance on Wednesday when Los Angeles take on his former team the Brooklyn Nets.
