I am seeing lot of arguments between Misbah's supporters and Arthur's fans. Here is my analysis without bias :
1) Its hard to digest people still support Misbah after what he has done recently. If he can play Irfan who was huffing, puffing, and talented ones who failed miserably, that means he has poor lack of knowledge as Chief Selector. Now he was not able to get any output from them, is an evidence that he is not a good coach either. The people who think Umar Akmal, Shehzad, etc. are still talented, should go and check India also had line of mediocre players like Manoj Prabhakar, Raju, Prasad, Mongia, etc. in their darkest eras who's just played 100s of games and you still can't remember any good games they won for the team.
And Misbah the legend going back to these options is incomprehensible given he has given all powers. You can argue, many times Mickey did not get what he wanted in the team because different person being selector.
2) Misbah played or captained almost his entire career in Abu Dhabi/UAE. When he himself went to South Africa and Australia, his own record is abysmal. Ajmal's chucking helped him a lot. You can say he won the games in SA, India and Asia Cup 2012. Then to remind every one , coach was Dav Whatmore, not Waqar Younis. Similarly , in 2016, when Mr. best captain went to England, then Mickey was coach not Waqar Younis. So, if someone is criticizing Mickey for not giving any result, they should check records properly. People say Mickey lost to SL in UAE, I think losing in front of home crowd by SL C team is far worse. And believe me , there is no guarantee we will win something in UAE too.
3) Records of coach captain-combination : I will take major series, and where it played
Misbah's +
===========
England Test in UAE 2012 : Misbah - Mohsin
Pak tour India ODI 2012-2013 : Misbah - Whatmore
Pak tour SA ODI 2013 : Misbah - Whatmore
Asia Cup 2012 : Misbah - Whatmore
Pak tour England 2016 : Misbah - Mickey
Aus tour UAE 2014 : Misbah - Waqar
Sarfaraz +
===============
CT 2017 : Sarfaraz - Mickey
Pak tour of England 2018 : Sarfaraz Mickey
Australia T20 tri series : Sarfaraz Mickey
4) Where I give Mickey benefit of doubt :
When he joined in 2016 Pakistan started playing continuously from England series to WI series to NZ to Aus. and if Misbah was so great, he could have done something in Australia & NZ test series in 2017.
Secondly, Mickey had to fight a lot to keep under-performers outside the team. Prime example UA, Shehzad, he also dropped Hafeez as well. Their record was far worse than Sarfaraz during whatever games they played
Involvement of Inzamam during WC 2019.
What you expect coach to do when your senior most batsmen throw their wickets and match against NZ and SA in tests? And we made him a captain of test team instead of dropping him. In any other country after that performance, players are not recalled. With Mickey, many matches we lost we could have won. In Misbah's era we played so pathetically that without the start of second innings we would have known team has lost already.
5) Where Mickey failed : 1) Keeping mediocre performing Sarf in team. 2) Over relying on Faheem Ashraf. I think he badly wanted him to become Klusner. But it is joke now. 3) Considering spinners as second fiddle role.
In conclusion : Its hard to change the mindset & work ethics of individuals. If we say, Mickey will do the same that he won't play proper spinners in future, same applies too Misbah. Nothing against Misbah, but he was not fit for captaincy role even in 2010.
