Nyet, as in no and not yet.

That’s Ilya Kovalchuk’s stance on the push to entice him to play for St. Petersburg in the Russian KHL next season.

It would take the Russian equivalent of opening Fort Knox to entice the Devils’ superstar left wing, who will become an unrestricted free agent on July 1, to make up his mind now to play in the KHL next season, an informed source told The Post.

The source insists that ultimate splurge has not yet occurred, disputing reports out of the world championships in Germany that said Kovalchuk already had agreed to a one-year deal in Russia next season.

The word is that unless blown away by a record Russian offer he can’t refuse, the 27-year-old is intent on waiting until July 1 to evaluate all his options, including playing in Russia.

As perhaps the most desirable unrestricted free agent in history, Kovalchuk is said to be very interested in remaining with the Devils, who in turn have made their very high degree of interest clear to the two-time 52-goal scorer.

Kovalchuk was captain of the Russian team that lost the gold-medal match to the Czech Republic 2-1 yesterday in Germany.

The Devils acquired Kovalchuk and defenseman Anssi Salmela from Atlanta on Feb. 4 for Johnny Oduya, Niclas Bergfors, prospect Patrice Cormier, a first-round pick and a swap of second-rounders.

Kovalchuk, who made $7.5 million last season and can expect offers exceeding $9 million, had 10 goals and 17 assists in 27 games with New Jersey and led the Devils with six points in their five-game playoff series loss to the Flyers.
