Janakantha report is emphasizing on the non-availability of Naimur Rahman and Mushfiqur Rahman.
But I think the main problem would be the fast bowling department - bowling with the new ball. The Janakantha report has not mentioned anything about Sharif or Mashrafe.
Because, Talha Jubair has not played any One Day International matches and as far as I've seen him in the test matches, he can't maintain a good line and length to the left-handers.
Tapash Baisya is a good second string bowler, but he gives away far too many runs to take a wicket.
I am not saying that Sharif or Mashrafe would have been more economical, but still, they can be compared to Manju.
But Manju cannot be compared with either Talha or Tapash because of their inexperience as a one day bowler.
