Alan Burrows has insisted Aberdeen will be "difficult clubs to deal with" if teams want to sign star strikers Duk and Bojan Miovski.
The Dons chief executive says Barry Robson wants to keep hold of the pair who have struck up a potent relationship in front of goal so far this season. Aberdeen sit in third place in the league five points ahead of Hearts in fourth with just five games remaining in the Premiership. Robson, who was appointed on a permanent basis earlier this week, takes his seven wins in a row Dons team to Ibrox on Sunday to face Rangers hoping to maintain a strong lead over the Jambos.
Miovski scored the second Dons goal when Aberdeen beat Michael Beale's side 2-0 at Pittodrie last month. It was Beale's only loss to a side that wasn't Celtic since he was appointed Gers manager last year. Duk and the North Macedonia forward have been linked with moves away after only one season in the Granite City but Burrows is adamant the club will keep hold of the pair.
