The first match in Dubai ended in a draw while the second match is now being played at the Sheikh Zayed Stadium in Abu Dhabi.
Earlier on the second day, the hosts had bowled the men from Down Under for a paltry 145 in response to their first innings total of 282, with seam bowler Mohammad Abbas the chief destroyer with figures of 5/33, ably assisted by Bilal Asif, who took 3/23.
The former England captain may have scored nearly 8,000 global runs and 18 Test centuries, but he says Abbas is the type of bowler that would make him "poop his pants".

It was an unceremonious end to what had been a commanding knock from Azhar, whose stroke-play off the back foot was a highlight through Pakistan's innings.
Azhar Ali clipped a ball off the edge of his bat and watched as it raced away towards the boundary.
"The Australian system has invested a lot of time, money and effort into those guys and at the moment, in recent times, they just haven't done it".
After a tiresome opening period, the embarrassing dismissal of Azhar brought the day to life.
But Mitchell Starc picked up the ball less than a yard from the boundary and threw it back to wicketkeeper Tim Paine, who ran Azhar out, leaving the Pakistani duo - who have combined the experience of 130 Tests and over 9,000 runs - stranded and looking bewildered.
