The 38-old-player joined Esteghlal on an 18-month contract for an undisclosed fee.
“I am happy to come to Esteghlal. I want to quit in the team. I want to help Esteghlal, that’s why I am here,” Enayati told Esteghlal’s website.
Enayati started his professional career in 2001 with Adonis. He has also played in Iranian clubs Abu Moslem, Sepahan, Saba and Mes.
Enayati reunited with his former coach Amir Ghalenoei in Esteghlal, where he scored 55 goals in 78 games across two different spells.
