Crestfallen England captain Eoin Morgan admitted that his team failed to live up to his expectations and eventually made an exit from World Cup at the league stage.
Bangladesh defeated England by 15 runs Monday and with this loss ended England's chances of qualifying for the quarter-finals.
Bangladesh and Sri Lanka have now joined tournament co-hosts Australia and New Zealand in progressing to quarter finals from Pool A. Visibly upset and dejected Morgan said: "My expectations were a lot higher than the way we've performed, so that's extremely disappointing.
"We picked guys who can play a brand of cricket that, if we performed, we could win this World Cup. Ultimately we haven't performed." After winning the toss England put Bangladesh in to bat who posted 275 in 50 overs losing seven wickets.
However while chasing England were bowled out for 260 despite half-centuries from Ian Bell and Jos Buttler and an unbeaten 42 from Chris Woakes. Banladesh's Rubel Hossain took the last two wickets in three balls to show England exit door. He finished with 4-53.
Morgan said: "I thought the guys bowled well, the Bangladeshi guys batted well but with a short boundary and the wicket the way it played, it was certainly within our reach.
"Today's an example where some of the guys performed but we didn't perform as a unit. We've done it for quite a while now. Since we landed in Australia we've tried to address that but it hasn't worked. "It's pretty poor, to be knocked out of a World Cup this early is unbelievably disappointing.
"It's obviously a surprise that we're knocked out this early. There'll be a lot of questions over the next few weeks as to what happened and what went wrong, and then we'll go from there.
"I'm gutted at the moment, we've struggled and fallen away since we arrived here. One of our big things was to fight back and to try and get through to the quarter-finals and then from there we could fight our way through the last three games, but it obviously that's not meant to be."
Bangladesh's win was set up by Mahmudullah's first one-day international century - also his country's first in a World Cup - while captain Mashrafe Mortaza picked up the wickets of Alex Hales and Joe Root before Rubel took centre stage.
Mortaza said: "Everyone's so proud. Thanks to the team management and coaching staff, they've put in really good effort with us, and obviously the boys. "We thought (275) was pretty good, we had to bowl well and in the middle we bowled really well and put pressure back on England.
"Mahmudullah was tremendous, he showed what he's got in his first hundred for Bangladesh. Also Mushfiqur, I have to mention his name because he was absolutely brilliant. "I have to say Rubel's name, he's very happy now, he got four wickets and they were very crucial wickets."
England looked to have been given a crucial lifeline in the 48th over when Tamim Iqbal dropped Woakes on the long-on boundary.But England were unable to get the Warwickshire all-rounder back on strike and Mortaza was able to celebrate a place in the last eight as Rubel bowled Stuart Broad and then Anderson with excellent deliveries.
"Tamim felt really bad, he's one of the best fielders for us," he said of the nervy finale. "That happens in cricket but we ended on the winning side so we're very happy. "It's amazing, it's for all the people at home working hard and out there supporting us. This is for you guys."
