PCB was also in favor of hosting the matches in UAE/Oman, since they would have received gate collections. But the other boards were against that idea.
And I also think that this PCB favor was good and It would have been better if the Asia Cup was played in UAE/Oman because now first the teams will go to Pakistan and than to Srilanka.
By the way I am in the favor of this decision which has been made by ACC. Means It was the Asia Cup and it should have been played in Asia so they have made a good decision I think.
