Bowling coach Heath Streak has pinpointed seamers Rubel Hossain, Shafiul Islam and Al-Amin Hossain as key to Bangladesh's bid to defeat Zimbabwe, come the first Test, which will start on Saturday.
Zimbabwe's set up for the tour to Bangladesh has been boosted by the news that Craig Ervine and Greg Lamb have reversed their decisions to stay away from the side, following an improvement in payment conditions.
Wicketkeeper-batsman Mushfiqur Rahim has retained the Test captaincy, while fast bowler Mashrafe Mortaza has been named the new ODI captain ahead of Bangladesh's series against Zimbabwe.
