Polli played for Nassaji last season, but after Nassaji’s relegation from the Iran Professional League (IPL), he left the team.
Currently, IPL champions Tractor are in negotiations to bring him aboard.
Tractor goalkeeper Alireza Beiranvand is likely to face a suspension due to a contract termination violation with Persepolis. In this case, Tractor will enter negotiations to sign the Brazilian goalkeeper.
