Newcastle Jets defender Ljubo Milicevic's name is the latest to be linked with new club Melbourne Heart.

The ex-Melbourne Victory man's contract ends at the end of the season and with the proposed move of his good friend Josip Skoko to the Heart, a move may be likely for Milicevic.

At present it is merely speculation as pointed out by Heart operations manager Joey Didulica.

"We have tried not to discuss individual players [in the media] until they have been signed and the players are comfortable with that being released," he said.

"We have written to every club and indicated we intended to speak to several players.

"Ljubo could be one of 50 or 60 players in theory we could have spoken with.

"We are not inclined to discuss hypotheticals because it would not be fair to Ljubo, who has a job to do in Newcastle."
