Crisis-hit Red Star Belgrade are caught up in a remarkable bust-up ahead of their Europa League match with Rangers after Serbia boss Dragan Stojkovic filed a lawsuit against the club's general manager Zvezdan Terzic.
Raging Terzic slaughtered the standard of refereeing in Serbia after Partizan Belgrade were awarded a controversial penalty in their weekend game, which they converted to stay two points ahead at the top of the league.
The Red Star chief accused Stojkovic - remarkably, an ex-Red Star player and even president - of 'directing a robbery' against his club, being behind all the refereeing decisions and in favour of Partizan Belgrade.
And a storm is brewing before they take on Rangers as Gio van Bronckhorst 's side eye the last eight.
That outraged the Serbia boss - who made over 100 appearances for Red Star before moving to Marseille in a £5.5 million move in 1990 - who responded by slapping in a lawsuit against Terzic.
He fumed: "I was sick when I read the accusations, untruths, disgusting and dirty low-budget lies about myself.
"This is not the first time Zvezdan Terzic has said that about me. I ignored it before, I had to focus exclusively on the national team, on qualifying for the World Cup.
"But this time, Terzic crossed the red line and put me in the position that I have no choice. I will protect myself, my integrity, reputation and honour legally, in court.
"I do not want to tolerate such insults and slander."
But Red Star have doubled down on the criticism and accused the national manager of having a vendetta against their club.
They stated: "With this announcement, Dragan Stojkovic continues to harass Red Star. We see this lawsuit as additional pressure on our club.
"Regardless of Stojkovic's threats, Red Star will not give up the fight to protect its interests. We are focused on the match with Glasgow Rangers and we will say everything we have to in court."
