Shere Bangla National Stadium pitch is always known as bowling friendly. Bangladesh had won a T20 series against Australia by 4-1 in that pitch. Therefore, I'm not going to be surprised if Pakistan gets whitewashed by Bangladesh there. Understanding the pitch condition is the key point here to bat well. Pakistan is blaming the pitch for the defeats instead of accepting their overall mistakes.
After watching 2 matches between these countries and Bangladesh recent performance in Sri Lanka I am expecting they are going to end this series with 3–0 because Pakistan is down and out of touch which is going to be worst for them.
Few minutes left in start of third and final game Pakistan having their lesson never underestimate any team specially while you are visiting them Bangladesh have timely good performance and consistency which allow them to have 4 wins out of last 5 T20i games which are good for them. Their bowlers are doing good, and they are giving tough time to their opponents while batting is also having some depth but still needed good improvement which allow them to have more runs on board which helps their bowlers for defending title.
