Abu Dhabi- Australia are facing the prospect of being asked to follow-on against Pakistan after the tourists lost four wickets on the third morning of the second and final test to slump to 120 for five at lunch in Abu Dhabi today.

Resuming on 22-1 after Pakistan had declared their first innings on 570-6, Australia lost David Warner, Glenn Maxwell, Nathan Lyon and Steve Smith to find themselves staring at a heavy defeat at Sheikh Zayed Stadium.

Captain Michael Clarke (34) and Mitchell Marsh (eight) were at the crease with Australia still needing 251 runs to avoid the follow-on against a Pakistan team eyeing their first series win against the visitors in 20 years, having won the opening test in Dubai.

Clarke was the only batsman to show positive intent as well as the temperament to offer some resistance to Pakistan's bowlers.
