Most pitches in Mirpur and Chittagong are spin bowling friendly. In Mirpur too we saw that India did not prioritize the spin bowlers. India management should have given chance to spin bowlers. But they don't do it. India was badly defeated in both the matches. They could have defeated the Bangladesh team in both the matches if they got some more help from the bowlers. In the last match, probably the Indian management will not make mistakes. They will make some changes within their squad. The spin bowlers are likely to be given a chance, as they have already lost the series. India will definitely not want to lose all the matches in the series.
I don't think that spinners such as Axar and Shahbaz are suitable for these conditions. I would have preferred someone like Ravichandran Ashwin or even Yuzvendra Chahal. Washington Sundar did his job well, but the same can't be said about the performance from Axar/Shahbaz in the first two matches.
