In his first comments since free agency began, Knicks rookie head coach Derek Fisher said he made a guarantee to Carmelo Anthony: The club will be better next season because of the new system.

Anthony has yet to make a decision about his future, and Fisher wouldn’t say if he felt good about the Knicks’ chances. Fisher met with Anthony in Los Angeles on Thursday, along with team president Phil Jackson and general manager Steve Mills.

After conducting his first official summer-league practice, Fisher said of his message to Anthony:
“He wants to win, wants to be successful,” Fisher said. “The time I had the visit with him, I just shared with him we’ll be a better basketball team because we’ll play the game a better way, play as a team, play with a system and format to allow the game to be easier for him and his teammates.

“I’m not sure if it hit home. … Hopefully we’ll find out soon.’’

Anthony visited the Bulls, Rockets, Mavericks and Lakers and still could somehow wind up in Miami in a new Big Three if Chris Bosh bolts to Houston. The Knicks are considered the front-runners, but Fisher said hasn’t spoken to Anthony since the LA meeting.

“He said he’d take some time with his family before he decides what his future would be,” Fisher said. “We’re all kind of in a wait-and-see mode like everyone else.
