Loss exposes Pakistan frailties
It is hard to pin-point one single reason for Pakistan's capitulation in Dubai; there were many chinks in their armour

Where is the home advantage, asks Misbah
The unresponsive pitches in the UAE that have not played out to Pakistan's strengths have left the team disappointed and bewildered. After losing the second Test against Sri Lanka in Dubai, Misbah-ul-Haq said flat pitches were not what he had wanted and it blunted the home advantage.
"Obviously, we are not getting support as per our strength [of spinners] and that is a worry for us," Misbah said. "The PCB is not preparing pitches, obviously the curator [in UAE] is preparing pitches. But as far as satisfaction goes, it's not there because we have not given instructions for such flat tracks.
"Maybe the groundsman wants to make another kind of pitch but they are not able to do that. It is surprising that there is no turn here on the pitch. Normally the pitches here help spin, on the second or third day but even on the fifth day the pitch did not spin."
Pakistan's top order was praised for their contribution in the first Test but their failure in the second means the team will have to take a fresh look at their options. The No. 3 position remains a talking point after Mohammad Hafeez, drafted back into the Test side after a stellar run in the ODIs, couldn't reprise the same form, scoring 21 and 1 in the second Test. Ahmed Shehzad's introduction as an opener didn't work either; the move disturbed the left-right combination of Khurram Manzoor and Shan Masood which had set-up Pakistan's win against South Africa in Abu Dhabi in November.
Pakistan's over-reliance on Younis Khan and Misbah-ul-Haq is no secret and it's high time other batsmen started delivering. The technically sound Asad Shafiq, who scored a century against South Africa at the same venue three months back, has been struggling since. Though he played some elegant back-foot shots on the fourth day, he wasn't able to stay for an extended period; he contributed 6 and 23.
Saeed Ajmal has toiled for 114.2 overs in the two Tests in this series and conceded 248 runs. On top of the workload, he also took a blow on his foot while batting in the second innings. It can be argued that Sri Lanka batsmen played him with caution and neutralised him well, but he did look off-colour with his line and length.
Rahat Ali, who went into the series as the second seamer, failed to make an impact in the two Tests. His inability to pick up wickets was excused by the captain, the coach and the team manager, who suggested the bowler had been unlucky. But for someone who bowled more than 100 overs in the series for just two wickets, it can't be just about luck. It also points to the lack of skill.
Dav Whatmore's tenure as the coach of Pakistan is soon coming to an end; he is with the team for another nine days. In the two years with Whatmore at the helm, Pakistan didn't show any signs of improvement and failed to win a single Test series. The record will leave a blot on Whatmore's coaching credentials.
