Majstorovic has taken the job after leaving AEK Athens and was asked about his good friend today.
"We'll probably have to wait for a long time, but you never know," said Majstorovic, laughing, according to Sportbladet.
"We have continuous contact and we have spoken to each other. But that he should come here is far away."
