Newcastle Jets defender Nikolai Topor-Stanley has turned down a new contract offer from the club.

The 25-year old centre-half rejected a deal that would have made him the club's highest-paid player according to Jets executive chairman Ken Edwards.

"It was a very, very good offer and it would have made him best-paid player on the team outside of a marquee signing," Edwards said yesterday.

"While the offer has been withdrawn, we've not given up on Topor-Stanley changing his mind.

"We made him the very best offer we could, but he asked for more. The Jets are not in a position to give him more."

Topor-Stanley joined the Jets from Perth Glory in January, 2009 and has emerged as one of the premier central defenders in the A-League in the last few seasons but it seems his future at the Hunter club is now uncertain.
