It was probably fastest pace derby i ever saw and i watched pretty much lots of derby. Esteghlal was kind of unlucky, Persepolis had better plan, send the ball behind slow Esteghlal defense.
In Esteghlal defense, they were without Cheshmi and Mohsen Karimi, two of their best players and lost Adil Chihi very early in game, the guy level is much higher than IPL, don't know what he is doing there.
Persepolis relying big time on Ahmadzadeh speed.
