He is playing tricks, which I don't like - confrontation is better than compromise.
Probably, his contract has some clause which secures his payment terms, hence he is happy to play around. Also, he knows, after him, PCB will have to come in BD or Kenya if they are to hire a foreign coach. For example, recently he backed Misbah to continue for some time, which is absurd, simply can't be true. What I understand is, he is trying to have Misbah as his shield - frankly speaking, after Oval, PAK's Test performance is shambolic, but hardly anyone has pointed fingers to Arthur - everything is dumped on Misbah's head; therefore I would have also backed the dummy, who keeps my cloth dry & clean.
What he is doing is allowing things to drift below until it reaches to crashing point. I have read him, I have seen his teams - no way, this can be his team, no way. I might be wrong, but what he is doing is probably setting his grounds for a land slide change. 35 years back, in BD cricket was played mostly in Dhaka/Chittagong & we had genuine shortage of minimum standard cricketer - therefore, often teams were over aged (basically few players playing in Leagues at home or in UK, kept playing till late ages), yet that wasn't like this. And, that's 29 months before next WC!!! I sense a big change from WI tour or at latest CT 2017; which will start from Captain.
I can tell you that, if Arthur was in charge, Amir would have been ODI vice Captain under Sarfu by now, if not Captain him self - just one example.
