Mehrab Hossain may not look prospective but yes, he had done well to make his way into the International arena before. Unfortunately, he could not carry on. He played one or two good innings but that was pretty much it. Can't rule him out from the Test considerations if his form is considered. Will surely make it into the current benched lot.
"Surely Allah does not do any injustice to men, but men are unjust to themselves." - [Al-Qur'an - 10:44]
