I blame previous coaches for this, they used to play with the same group of players for 7-8 years. which exhausted them physically and mentally. I see this year Kolakovic started to add new players to the team, he also has Manavinejad to replace Ghaemi/Mirza in the starting lineup who got injured in his flight from Italy to Iran (according to himself)
I think they should start Manavinejad over Ghaemi/Mirza, I think he might already be better
