Iran Press/Iran news: Esteghlal, in their usual blue colours, played well in the first half, and managed a 0-0 draw at half time.
However, in the second half, Qatar's al-Duhail piled on the pressure and scored three times for an emphatic win, giving Esteghlal a bitter start to the AFC Champions League 2019.
The Blues have an uphill task ahead of them, being in the same group as Saudi Arabia's al-Hilal, UAE's al-Ein, and Qatar's al-Duhail.
Just like last year, Esteghlal have their work cut out in the AFC Champions League 2019, finding themselves in one of the toughest groups of the championship. 103
