The Windies captain said his side had played competitively throughout the year and the remaining matches in the series offered more opportunities for them to make headway.
The visitors crumbled to a seven-wicket defeat in the first ODI on Friday at the Sheikh Abu Naser Stadium, after they failed to fire and the Bangladeshis seized the chance to take a 1-0 lead in the five-match series.
“It does us no good hitting the alarm or panic button,” Sammy told WICB Media. “We just have to admit that we got a little complacent and Bangladesh seized on the opportunity. It was the first ODI of a five-match series and we have to put things right [on Sunday].
“We have been playing good cricket for the last six to 12 months. We know what we have got to do. We have to put runs on the board and our batsmen, who have been very responsible for the last few series, will need to do it again and we need our bowlers to back it up.
“We need to get back to the basics, the things that have worked all year long for us, and put on a good display of cricket which we know we can do.”
Sammy said West Indies simply did not play the way they have been playing in recent times in the first ODI.
“I think the way our batsmen, including myself, were dismissed, there were too many aggressive shots and they were not necessary at the time,” he said.
“Our shot selection obviously, was not very good, but we just had a bad day at the office, and we have got to move on and come back strong in the second ODI.
“We always have respect for our opponents – but we know if we play to our full potential we can beat any team and we will have that same confidence on Sunday. We will look to execute all the plans we had and do it properly.”
Sammy rejected suggestions that the fielding restriction regulation, which has inevitably created more gaps in the field for batsmen to score contributed to the way his side batted in the first ODI.
“I just think we didn’t exercise enough patience and we did not bat in partnerships, and in turn we got what we deserved,” he said.
