Carmelo Anthony already has claimed Knicks fans should not expect a championship this season.

But the playoffs are another matter. In fact, Anthony on Monday asserted his belief the Knicks “absolutely” will be back in the playoffs after missing out last season.

“Yeah, I think so for sure. Absolutely,” an impressively slimmed-down Anthony said of the Knicks’ playoff chances before entering a Midtown gym for a late morning-to-early afternoon workout with a group of NBA players.

Anthony snuffed an attempt to establish any goals for the revamped Knicks, who will enter their first full season under team president Phil Jackson and new coach Derek Fisher.

“I can’t wait to get started,” said Anthony, who missed the playoffs for the first time in his career when the Knicks stumbled to a 37-45 record last season. “No goals. Not setting any goals, but I just can’t wait to get it back on.”

And Anthony showed some of that desire Monday in the closed, high-caliber workout with assorted NBA players. One of the participants, who asked not to be named, said Anthony “clearly was the best player on the court. He didn’t take a lot of shots but he was very efficient. He looked like Melo. He looked like he had something to prove.”

The Knicks, of course, will have a decidedly new look. Among the departed are Tyson Chandler, Raymond Felton and Jeremy Tyler. New faces include Samuel Dalembert, Jose Calderon, Travis Outlaw, Quincy Acy, Jason Smith, Shane Larkin and Cleanthony Early.

Of the moves, Anthony said, “I’m cool, I’m happy, but I don’t really want to get into details about that.”
