Interesting stat. Razzak averages 15.33 with the ball in Bangladesh wins in ODIs, taking 120 wickets. What's more him alongside Mashrafe, Shafiul and Rubel from the current crop have better bowling averages in wins, then Shakib al Hasan.

It shows how pivotal Razzak is to Bangladesh but gets nowhere near the recognition he deserves.
