Bangladesh captain Shakib Al Hasan pledged his team would "fight to the end" to secure qualification for the World Cup knockout phase after a dramatic win over England on Friday.
The home side restricted England to 225 all out and made a good start to their reply, looking comfortable at 155-3 before a collapse saw them lose five wickets for just 14 runs.
But Mohammad Mahmudullah (21) and Shafiul Islam (24) took the score from a perilous 169-8 to 227-8, guiding Bangladesh to a nervy two-wicket victory.
"I thought Mahmudullah and Shafiul batted exceptionally well. At one stage we thought we'd lost the game but they showed their character, how tough they are and how hard-working," said Shakib.
"I thought we'd lost the game but they just played outstandingly. I can't describe how well they batted," he said.
"It means a hell of a lot to the whole country. We all know we're very emotional about cricket."
The skipper acknowledged it would still be tough for his side to qualify and they would probably have to win both of their last two matches against the Netherlands and South Africa to stand a chance.
But he said: "It was a great win for us and hopefully we'll kick on from here. No matter what happens we'll fight to the end."
Disappointed England captain Andrew Strauss, who missed out on the chance to guarantee qualification to the knockout phase, said: "We wanted to win this game and win it well.
"We struggled a little bit with the bat although I thought 225 was a competitive total. We needed to bowl and field well but didn't do that as well as we would have liked. We got ourselves in a great position to win the game but in the end we couldn't take those final two wickets.
"We're bitterly disappointed and we have to bounce back well against the West Indies (in Chennai on Thursday)."
Strauss blamed the loss of early wickets in the England innings and said his bowlers had not used the new ball well.
"We fought hard. We got ourselves in a position to win the game but we weren't able to put the final nail in the coffin," he said.
"We're very disappointed. It was a missed opportunity for us but you can't dwell on it too long, you've got to look forward," he added.
