Ganguly is not Bangladeshi. Wasim Akram is not a fulltime coach. Not sure about the level of certifications our coaches have. Aminul Islam is working with the Asian Cricket Council and was in charge of China. Salahuddin is going to work with the Academy in Malaysia. I think another of our ex-bowlers (Saiful or Monjurul) is also probably working with the Chinese Womens' team.
I guess at this stage it is probably more beneficial to have a foreign coach.
Where is the kaboom? There was supposed to be an earth-shattering kaboom!
