"It is unfortunate. It should have happened," Shanto said. "But we can't spend too much time talking about it on the day before the Test match. [Shakib's arrival] is not in our control, so we are not spending too much time thinking about it. We have to focus on the two important Tests and that's what the players are doing. We had plans to send off one of the world's best players. All of us personally feel that it remains pending."

Shakib's future as a Bangladesh player was put in uncertainty following the upheaval of the Bangladesh government in August; Shakib was a member of the political party that was overthrown. Shanto said the players were focused on the cricket, which is why they hadn't spoken on the matter.

"Our focus is on winning the Test that starts tomorrow. We would have been happy if it was his farewell Test. We all know why he is unable to come."

Shanto said replacing Shakib was going to be tough. He said Mehidy Hasan Miraz has shown he can step up but it would take him some time.

"It is hard to match [Shakib], especially for the captain. He would usually allow us to play the extra batter or bowler. Now the No. 7 becomes a crucial spot. We don't have anyone exactly like Shakib bhai but Miraz can be a very good option. He is bowling and batting superbly. There are more responsibilities, which Miraz is prepared for. He has improved his batting. He is taking the team to good positions, if you look at the last few Tests. I would hope that Miraz can take that place in the next couple of years."

Uncapped left-arm spinner Hasan Murad replaced Shakib in the squad for the first Test. Shanto said Murad deserved the call-up, and expressed confidence in his spin attack.

"We have four quality spinners in the side. Hasan Murad has an outstanding first-class record. He bowls well in all types of wickets. It is a deserving selection. Nayeem couldn't break into the side despite playing well recently. Whether we pick three or four spinners tomorrow, they are all capable. Regardless of our combination, we will give our best."

Bangladesh go into the two-Test series against South Africa after winning their maiden series in Pakistan 2-0, before losing 2-0 in India earlier this month.
