Surely not looking good for the Bongs. Their best bet would be a slow pitch, they shouldn't risk anything with any experiment in terms of Spin friendly deck.
Sri Lankan spinners such as Hasaranga are in top form right now. If Bangladesh prepares a spin-friendly pitch, then it will backfire upon them and I won't be surprised if they get bowled out for two digit totals. This is something that they should avoid at all cost. A safer option for them would be to prepare tracks that are more conductive for batting. Anyway, the first test match is scheduled for tomorrow. It will take place at the Zahur Ahmed Chowdhury Stadium in Chittagong, which is notorious for it's spin-friendly track.
