The Football Federation of Iran (FFIRI) have announced they were going to suspend all links with the Greek Football Federation (EPO) after Greece cancelled a planned friendly match between the two sides earlier in May.
"The Football Federation of Iran expresses deep regret at the Greek Football Federation’s lack of respect and ethics,” the FFIRI said in a statement which was published on their official website.
"We will provide a report to FIFA and will use all the legal possibilities to obtain compensation for all sporting and financial losses we have incurred.
"We will suspend all links with the Greek Football Federation until FIFA considers our report."
Iran, who have qualified for next month’s World Cup in Russia, were due to play Greece on May 12, but the match was cancelled. The FFIRI said this has seriously damaged Iran’s training programme for the World Cup.
Talks were later held with Kosovo regarding a potential friendly, but the Kosovan Football Federation pulled out of the idea.
Russia will host its first-ever FIFA World Cup from June 14 to July 15, with Iran set to play Portugal, Spain and Morocco in Group B.
Iran’s only remaining friendly before the tournament will be held on June 8, they will take on Lithuania in Moscow.
