Problem is, in Iran at the moment attacking players/midfielders are of an abundance. Half decent reliable CB's are like rare diamonds. Unless you buy foreign CB's, there is honestly not that many decent Iranian CB's to pick from unfortunately.
Pourghaz, i agree. He is not very good, but for IPL standards he will do the job. Considering that Sepahan wont be playing in AFC CL they will get away with such a signing, for now.
