Ramezani, 28, was deemed surplus to requirement last week and joined Persepolis’ archrival Esteghlal for an undisclosed fee.
Ramezani joined Persepolis in September from Saipa but failed to live up to the expectations.
Esteghlal had already signed Persepolis defender Mohammad Naderi at the beginning of the 2020-21 Iran Professional League season.
The Blues sit third in the table behind Persepolis and Sepahan.
