Ljubicic is the team’s primary objective, and Daniel Farke wants to add a midfield player before the transfer window shuts.
However, because Koln, a second-tier German team, is reluctant to lose the player, negotiations have been difficult.
Leeds made an earlier offer of €4 million, which the German side rejected, but the Whites are still unwilling to give up.
The German newspaper Bild (via Fussball Transfers) reports that Leeds plans to submit a revised and enhanced proposal for the Austrian midfield player in the near future.
Leeds is determined to bring him to Elland Road, and the player has expressed support for this move.
Ljubicic is pressing the German team to reach a deal since he is also adamant about moving to Leeds.
Although Koln signed him for free and would profit handsomely from his sale, the club is reluctant to let him go.
If they were to trade Ljubicic this summer, the German team would not be allowed to sign a replacement because they are now subject to a transfer ban.
