8. Mustafizur Rahman (Bangladesh)
The first international cricketer to win Man-of-the-Match award in his ODI and Test debuts respectively, Mustafizur Rahman was one of the major reasons behind Bangladesh’s roaring success in 2015. Specifically, the 20-year-old turned out be a hot property in the 50-overs format where he grabbed 21 scalps in merely 9 matches at an incredible economy of 4.26. Rahman’s twin fifers in the 3-match ODI series against India led Bangladesh to a historic ODI series win. Even on his Test debut, he impressed everyone with his 4-wicket haul against the Proteas. The Bangladeshi pacer is masterly adept in bowling cutters as well as varying his pace which makes him a tough nut to crack for the opponents.
