Shojaei has most recently played for AEK Athens but he will leave the Greek team.
The 34-year-oldmidfielder has been also linked with Cypriot Apollon Smyrnis and Indian club Goa.
Shojae is the only Iranian player who represented his country in three World Cups.
He has also played for Iran in three Asian Cups.
Shojaei played 68 minutes in the match against Morocco in the 2018 World Cup but was an unused substitute in two matches against Spain and Portugal.
