The 33-year-old international defender has joined Esteghlal on a two-year contract.
Montazeri started his playing career at Foolad in 2005 and joined Esteghlal after two years.
He left Esteghlal in 2014 to join Qatar’s Umm-Salal and signed a contract with Al-Ahli one year later.
The free agent defender joined Esteghlal Thursday night for an undisclosed fee.
Montazeri was a member of Team Melli in the 2014 FIFA World Cup and played full 90 minutes in all three matches against Nigeria, Argentina and Bosnia and Herzegovina, where Iran was eliminated in the group stage.
Montazeri missed 2015 AFC Asian Cup due to injury.
