According to Chris Tait in today's Greenock Telegraph, Moore has confirmed his interest in Jackson.
And although the Ton boss has admitted that he has spoke to St Johnstone about the player, he also reveals that he and Derek McInnes have not been able to reach an agreement on his wages.
"Andy Jackson is one we have looked at and we spoke to St Johnstone about him," Moore told Tait, "but it's not gone any further because of the wage demands.
"I had looked at his form since he came back from injury and inquired about him but myself and Derek can't reach an agreement on what we will pay for him and what they want."Greenock Telegraph: Loan Deal Move Hits Cash Snag (06.01.2011).
