Stefanidis has been subjected to repeated threats and intimidation from a section of the club’s fans since it became known last Sunday that he had agreed terms for a move to arch-rivals Malmö FF at the beginning of next year.
The player’s agent, Per Jonsson, is now hoping that the two clubs can come to an arrangement that would allow Stefanidis to move to Malmö earlier than planned.
“It is not feasible for him to stay here in light of the current situation,” he told Kvällsposten.
According to news agency TT, the player stayed away from Tuesday’s training session as a result of illness. The session was however attended by a number of police officers and security guards.
At earlier sessions, Helsingborg players – among them Henrik Larsson – have had to intervene to protect Stefanidis from the unwanted attentions of irate fans.
It has been forty years since the last time a player completed a move from Helsingborg to Malmö.
