In my opinion, they should focus on two coaches, and NOT one.
They have to put one on top of teammelli. They have to keep another involved with Iranian football somehow as an alternative and a POINT for the head coach that an alternative is always available if he does not perform.
Perspolees is tarbeeyat badani's property, isnt it? They have financial issues, dont they?
So, get a good coach for perspolees and keep him also as an alternative for Teammelli. that way, everyone would remain happy.
