Hearts have been told by Hammarby that they will have to pay a compensation fee if they are to prize manager Marti Cifuentes away from the Swedish club.
The 40-year old is believed to be one of the front runners to replace Robbie Neilson in Gorgie, with Steven Naismith taking the reins until the end of the season when the Scot was sacked back in April.
Spaniard Cifuentes is believed to have held talks with the Jambos hierarchy at Tynecastle, with interim boss Naismith still hopeful that he can land the job on a full-time basis. But now Hammarby chief executive Richard von Yxkul has revealed that Cifuentes, who is under contract until December 2024, won't come cheap and that the Allsvenskan side are determined to fight tooth and nail to keep him.
