The Bangladesh team returned yesterday after a successful West Indies tour in which they won their first Test in West Indies since 2009 and clinched their maiden T20I series in the Caribbean.

Although Bangladesh lost the ODI series 3-0, given that the team found new performers in the absence of players like Mushfiqur Rahim, Najmul Hossain Shanto, Towhid Hridoy and Mustafizur Rahman, there are many positive the Tigers can take out of the series.

Jaker Ali shone in all three formats with important runs, Shamim Hossain hit whirlwind innings down the order in the T20Is, Soumya Sarkar looked close to his classy best in white-ball cricket while Mahmudullah Riyad turned back the clock in the ODI series.

The pacers ensured that the hosts did not take the Test series 2-0 as their efforts saw the Tigers earn a series-levelling win in the Jamaica Test.

Speedster Nahid Rana rattled the West Indies in the second Test, Taskin Ahmed and Hasan Mahmud remained affective throughout the tour and all-rounder Mahedi Hasan proved more than handy with his off-spin in the T20Is and was rightfully named the player of the series.

But a series win should not take away focus from the deficiencies that exist in the team, felt Bangladesh's senior assistant coach Mohammed Salahuddin, saying it is high time for the players to start showing more consistency.

"We do have weaknesses, but it would not be right to talk about them publicly," Salahuddin told reporters on his return to the country yesterday.

"Although we won the T20 series, we have to begin working on those weaknesses. We can't take too long, if we wait, time would get away from us. After spending so much time [in international cricket], we [Bangladesh team] should be in a position where we can play consistent cricket," he added.

A lack of consistency has long plagued the players of the Bangladesh team with batters like Liton Das, who is going through a terrible patch, Afif Hossain and even Hridoy not being consistent at the highest level for long periods.

Inconsistency has been an issue in Soumya's decade long international career as well, however, in the while-ball series in the Caribbean, the left-hander showed composure and stuck to a process which helped him score runs.

Salahuddin said that players like Soumya are thinking more independently now which is helping their game and credited head coach Phil Simmons for giving players the freedom to think differently.

"The boys are getting used to playing with more responsibility. In our team meetings, they are getting involved and speaking up a lot more. We needed this very much.

"Our primary goal was to change their mentality. The head coach has given them a lot of freedom to change their way of thinking. I feel they are getting some success because of that. In the future, they can do even better," he said.

Salahuddin also spoke about how winning the second Test sparked their aggression for the rest of the tour.

"We got a lot of motivation from the Test series. From there we began thinking whether we should play to survive or become more aggressive. Usually what happens is that the players only think about themselves. How they are playing, how they got out, the boys mostly think about things like that.

"But when we began thinking about the opposition, we started playing aggressive cricket and that changed how we approached the game. This small change happened in the Test series. After that, we felt we have a good chance of doing well in the entire series."
