If we discuss the performance of the two matches, Sri Lanka has performed better than Bangladesh comparatively and they made some mistakes in the second match. If they work on those mistakes, then maybe we can see a better performance from Sri Lanka in the third ODI match and it might be that they defeat Bangladesh and secure the ODI series.
Bangladesh's first bowlers are not getting many wickets, so Bangladesh must focus more on spinners. Mehedi Hasan Miraz is not able to bat or bowl well. However, Tanvir Islam took 5 wickets in the last match and that is where the foundation stone of Bangladesh's victory was laid. Mustafizur Rahman is not able to provide any advantage but it is not the same in today's match so there may be some difference in the performance of the bowlers. The last two matches were played at Premadasha Stadium but today's final match will be held at Pallekele Stadium where there may be differences in the pitch for batting and bowling. However, as a Bangladesh supporter today, I will definitely keep Bangladesh ahead and hope that Bangladesh can play well in today's match and win the series.
