Waquar tried his best as well, but he wasn't technically competent or learned enough to transform his great will into action. Result was even worse - gap created between him & players who were scared of him & players took fitness drills as a burden, imposed on them.
also, we'll have to be fair with Waquar - his fitness regime demanded younger players, he was given a team officially 32+ average aged. Now, Arthur has started from the right lane - first has trimmed the average age of the side significantly (It'll go down further once MoHa, Wahab & Malik are shown the door), next he is making "old habit" live hard - in a years' time, if Arthur is still there, few players'll take self retirement, so that they can remain in one piece for PLs & SLs - Umar Akmal is just the start.
