Bangladesh cricket chief Nazmul Hassan said Shakib Al Hasan will remain as Test captain despite disliking the format and expressing his reluctance to stay on following this week's embarrassing defeat to Afghanistan.

Nazmul admitted the all-rounder had shown little interest or enthusiasm for the five-day game -- an attitude which would not have been helped by Monday's 224-run loss to Afghanistan in Chittagong.

"We have noticed he did not have much interest in Test (cricket). You have seen that when we were touring foreign countries, he wanted to have a break during the Tests," Nazmul told reporters in Dhaka late Wednesday.

"Naturally he might have less interest. But we never heard that he has less interest in captaincy. If he is skipper, then he has to play. If you are not skipper, then you can skip," he said.

Hassan's comments came after Shakib said he no longer wanted to lead the side in Tests following the chastening defeat to minnows Afghanistan, who were playing only their third five-day game.

Bangladesh became the first team to lose to 10 different Test sides with the defeat, which followed a lacklustre World Cup and 0-3 one-day whitewash by Sri Lanka in July.

Shakib, who shone at the World Cup with 606 runs and 11 wickets but was skipper for the Sri Lanka tour, said his performances might improve if he relinquished the captaincy.

"It will be best if I didn't have to lead," Shakib told reporters after the Afghanistan loss.

"I personally believe it will be good for my game.

"And if I have to continue leading, then obviously there is a lot to discuss about (with the board)," he said.

Hassan said he spoke with Shakib on Tuesday after the Afghanistan loss, but that the player did not raise any concerns.

"Our boys are emotional. I will speak with him when things get calm," he said.

Shakib will now lead Bangladesh in a tri-nation Twenty20 tournament involving Afghanistan and Zimbabwe starting in Dhaka on Friday.
