Bangladesh have already announced their XI for tomorrow, with the only change being the inclusion of Junaid Siddique in place of Mehrab Hossain jnr. Naeem Islam opened in the third ODI with little success, so he's likely to drop down the order to accommodate Junaid.
Bangladesh 1 Tamim Iqbal, 2 Junaid Siddique, 3 Mohammad Ashraful, 4 Shakib Al Hasan (capt), 5 Raqibul Hasan, 6 Mushfiqur Rahim (wk), 7 Mahmudullah, 8 Naeem Islam, 9 Mahbubul Alam, 10 Enamul Haque jnr., 11 Syed Rasel
Zimbabwe are yet to announce their XI, but it won't be surprising if they stick to their winning combination. Their top scorer in the second game, Sean Williams, missed the third, so there's a case for his inclusion. He could replace Vusi Sibanda, who was out for a second-ball duck.
Zimbabwe: (probable) 1 Vusi Sibanda/Sean Williams, 2 Mark Vermeulen, 3 Hamilton Masakadza, 4 Brendan Taylor (wk), 5 Charles Coventry, 6 Elton Chigumbura, 7 Stuart Matsikenyeri, 8 Malcolm Waller, 9 Prosper Utseya (capt), 10 Ray Price, 11 Tawanda Mupariwa
