Farideh Shojaei, a member of the club’s board of directors commented on the negotiations with Mazzarri.
Esteghlal parted ways with Pitso Mosimane in late January and is currently headed by Sohrab Bakhtiarizadeh.
The club has initiated negotiations with the Italian tactician.
Mazzarri, previously linked with Esteghlal's arch-rival Persepolis, managed Napoli in the 2023-2024 season but did not achieve significant success.
“We are closely monitoring the negotiations to ensure the contract has no issues. A thorough review of the details takes time, but we're committed to a smooth process,” she said.
