Team news
Pakistan are set to continue with their 3-1 quicks-spin combination, with Wahab Riaz replacing Hasan Ali, who misses the game with a back complaint. No other changes are expected.
Pakistan (probable): 1 Sami Aslam, 2 Shan Masood, 3 Azhar Ali, 4 Asad Shafiq, 5 Babar Azam, 6 Haris Sohail, 7 Sarfraz Ahmed (capt & wk), 8 Mohammad Amir, 9 Yasir Shah, 10 Wahab Riaz, 11 Mohammad Abbas

Sri Lanka (probable): 1 Dimuth Karunaratne, 2 Kaushal Silva, 3 Sadeera Samarawickrama, 4 Kusal Mendis, 5 Dinesh Chandimal (capt), 6 Niroshan Dickwella (wk), 7 Dilruwan Perera, 8 Rangana Herath, 9 Suranga Lakmal, 10 Lakshan Sandakan, 11 Nuwan Pradeep
Pitch and conditions
Dinesh Chandimal reckoned the pitch was similar to Abu Dhabi's in its dryness. Humidity levels will be high, something Sarfraz thought would assist the quick bowlers. How the pink ball plays under lights is, to a large extent, still an unknown quantity.
