Slobodan Rajkovic and Marcel Heller both want to depart SV Darmstadt 98 after helping them escape relegation last campaign.
The former has spent just one season Merck-Stadion am Böllenfalltor following his transfer from Hamburger SV whilst Heller joined the club from Aachen in 2013.
Darmstadt President Rüdiger Fritsch wants Heller to remain at the club, despite the 30-year-old declaring his interest to leave the Bundesliga club.
“We will not meet his request to be released,” Fritsch told SportBild.
Rajkovic has attracted interest from Serie A club Palermo, according to a number of reports in Italy.
