Nagoya Grampus manager Dragan Stojkovic believes a grenade thrown into the yard of his family home in Serbia was “99 per cent” the work of hooligans from his former club, Japanese media said on Friday.

The explosive device was thrown into the yard of the Serbian football great’s family home in Nis, in the south of the country, last week but caused no injuries or damage.

Speaking in Japan, where his Nagoya side finished second in last season’s J-League, Stojkovic said Serbian authorities had told him hooligans from his former club Red Star Belgrade had almost certainly targeted his home.

“It is an absolutely crazy act. Now we will let them get on with the investigation and wait for the result,” he said.

The 46-year-old Stojkovic, known by his nickname Piksi, was considered one of the former Yugoslavia’s best footballers.

But he has endured a torrid relationship with Red Star fans, despite being voted one of the club’s five best ever players.

In January he was chased from a bar at the Red Star Belgrade stadium by the fans of the club that he went on to head from 2005 to 2007.

After the incident, Stojkovic told journalists that he was never accepted by the fans while he was the Red Star Belgrade president since he did not allow them to “lead the club’s politics.”

After four years with Red Star, he moved to French giants Marseille where he won the 1993 Champions League.

He later joined Nagoya which was then under the tutelage of Arsenal boss Arsene Wenger.

He became Nagoya Grampus coach in 2008.
