Carmelo Anthony could be motivated by the treatment of Stephon Marbury by both the New York Knicks' organization and fans to leave the team in free agency.

Marbury sat four rows behind the Knicks' bench on Christmas Day, his first visit to Madison Square Garden in three years.

“He saw Marbury get heckled by some fans on Christmas,’’ one source told The Post. “He doesn’t want to be the next Marbury. He’s very sensitive.”

If the Knicks continue to spiral, Anthony will be the face of those troubles regardless of his production.

The Los Angeles Lakers, Los Angeles Clippers and Chicago Bulls are on his short list, according to a source. The Lakers have cap space, but a reunion with Mike D'Antoni would be unappealing.

The Clippers would need to acquire Anthony via a trade.

Anthony's preference is to remain with the Knicks if he sees a solid plan in place.
