The Icelandic international left the club at the end of his contract last month having delivered diminishing returns over the course of the campaign.
He did not play after the restart. The club felt he had returned unfit from Iceland, where he had been with his dying mother, whilst he also failed to agree to waive part of his salary like the rest of the squad, opting instead to give to charity.
Gíslason sees it differently, describing the club’s management, including coach Uwe Koshinat, as “rotten characters.”
“I was perfectly fit,” he insisted, speaking to Radio Regenbogen. “I followed the plans of athletics coach Dirk Stelly, I always ran. To help Sandhausen, I even missed my mother’s funeral. It’s bullshit if it is said that I was not as fit as the others.”
He continued by adding that that Koschinat had told him that he “wouldn’t be part of the team” if he had not sacrificed part of his salary, although Gíslason he was “joking”, believing the the waiver had been optional.
Club president Jürgen Machmeier said he was “perplexed” by the 32-year-old’s claims, saying he had stuck up for the player. He had earlier said that Gíslason had returned from Iceland “in a desperate physical condition” and would have been too much at risk of injury had he played.
Sporting director Mikayil Kabaca meanwhile has said that “if you have a season like Rurik behind you, you should better go inside than go in against your former club.”
Gíslason, who had over a million Instagram followers after his looks earned him attention at the 2018 World Cup, remains without a club and is also considering retiring.
Meanwhile, Sandhausen have confirmed that youngsters Yves Borie and Nnamdi-Morris Igbokwe have signed ‘local player’ contracts for the coming season.
League regulations require clubs to name four such players, with Sandhausen opting to hand deals to Borie and Igbokwe, who play for the under-23 and under-19 sides respectively. Neither are likely to be heavily involved with the first team.
Goalkeeper Benedikt Grawe, who is now part of the professional squad, and Shpetim Xhaka, another U19 player, are the other two local players.
