In his boldest statement of training camp, on the eve of their preseason opener against the Nets in Newark, Knicks coach Mike D’Antoni said the current group can win a championship this June, calling it a “reasonable’’ expectation.

“I think we do have the ability to win it all,’’ D’Antoni said.

In remarks made to WFAN’s Mike Francesa, D’Antoni added, “I think we have one of the best frontcourts in the game. We’re excited about trying to win a championship. We’re one of the top-tier teams. There’s no reason not to compete night in and night out and be in every game and be very good at the end.

“If we all come together, why can’t we compete for a championship?’’
