England have been set a record-breaking chase of 491 runs to overcome Pakistan on day four of the second Test.
The Green Shirts extended their advantage by the end of play on Saturday and, having seen three men fall in the morning session in Dubai, they opted to declare at 354-6.
England began their innings in a slow manner, with Moeen Ali edging Imran Khan's left-hander to Younis Khan for a simple catch for just one run, before Alastair Cook (10) was sent packing to make a tough task even tougher.
The skipper, carrying an injury which leaves his participation in the next Test in doubt, top-edged and saw his time at the stumps come to an end when Wahab Riaz claimed a smart catch to leave England's hopes in tatters.
Ian Bell and Joe Root kept things ticking over until the break, racking up 18 and 14 runs respectively, but with two men down and a record target to chase, things are looking bleak in the Middle East.
