he's simply not good enough to fill the shoes of Misbah and get promoted in the batting order. Too inconsistent, mentally weak, can't lead, can't score a big 100 or play at hight strike rate if required. At this point he dont deserve to play regularly, he can stay with the team but shouldnt play regularly, Salahuddin should get chances now.
We all saw how big of a disappointment he was in ODIs, now he is starting to prove it in tests too.
Last year was his biggest test but he ended up with a mediocre record when he was supposed to be at his peak. Most ducks in a calander year by a Pakistani test batsman, that's some record to have.
Management trust him though, he might not get dropped soon, he will save his place by scoring when it wouldn't matter much. His average is on the verge of being dropped below 40, as a test batsman for a big team, it is not acceptable at all, he is overrated.
