Bangladesh coach Shane Jurgensen has demanded a patient batting approach in the second Test against Zimbabwe in Harare.
Bangladesh were hot favourites to win the series but in the first Test they were hammered by 335 runs after being skittled out for 134 and 147.
Zimbabwe skipper Brendan Taylor scored two centuries in the match to show them how it should have been done.
The Bangladesh Cricket Board (BCB) was heavily critical of the performance, accusing senior players of not taking enough responsibility and suggesting some were not 100 per cent fit.
Fast bowlers Rubel Hossain and Shahadat Hossain have since returned home to be replaced by Shafiul Islam and uncapped all-rounder Ziaur Rahman for the second Test, which starts on Thursday.
Jurgensen rejected those criticisms but admitted: "We know we didn't play as well as we could have. We have come here to win but at the same time we know that Zimbabwe are a tough opponent.
"Losing a game is not ideal, especially as it was a game a lot of people may have expected us to win.
"But if you actually look at the record of Zimbabwe in their own country, they have performed quite well, so I don't understand why people seem to be very upset."
If Bangladesh are to avoid a Test series defeat, Jurgensen knows a major improvement in their batting will be required after their struggles against the Zimbabwe seam attack first time round.
"We didn't play with any patience and we need to improve that," Jurgensen said. "We just have to bat for longer. We did not last until the second new ball in each innings, we had no partnerships or players batting for long periods.
"We have to be very disciplined in our approach to every ball, and do our basics right on this surface, which is a little bit foreign to us."
Zimbabwe are, unsurprisingly, set to field an unchanged XI, and captain Taylor expects a similar performance from his side, and is keen to see them again exploit the attacking desire of the tourists' batsmen.
Taylor said: "We know that they are pretty attacking players and that if you starve them for runs, they create chances."
