England captain Stuart Broad believes his side now have the confidence to mount a serious challenge for the World Twenty20 title.
A stunning, unbeaten century from Alex Hales helped turn England's fortunes around as they pulled off a remarkable victory over the world's top-ranked Twenty20 side Sri Lanka on Thursday.
England still need to beat South Africa on Saturday to avoid elimination from the tournament, but Broad sees no reason why they cannot repeat their unexpected victory in the competition four years ago.
"T20 is a momentum game and the innings we chased against Sri Lanka was one of the best I've ever witnessed," he said.
"The confidence and belief we will get from that going into our final two group games is going to be huge. It's in our hands a little bit now.
"If we had lost against Sri Lanka we were pretty much out of the World Cup. With that sort of pressure, it's exciting to see players come through that.
"We have got two group games left and we're very confident we can do well in those.
"We know what these tournaments are like, if you can get on a run, if you can get a few guys going you can win these tournaments and it's not out of our grasp."
But Broad also warned that his side need to make vast improvements in the field having put down a number of catches against Sri Lanka, who took advantage of their reprieves to score an imposing 189-4.
"Our batting is obviously firing but we need to up the standard of our fielding," the skipper added.
"Our fielding has been our strong point in the last three weeks, we have been awesome, so to miss chances against key men hurt us.
"We could have easily restricted Sri Lanka to 150 on that wicket: we could have done, but we didn't.
"If we take our catches we will stand ourselves in a much better chance on Saturday."
England's opening two matches have been under floodlights, and evening matches in Chittagonghave been badly affected by dew so far, making the ball hard to grip for bowlers and tricky to cling onto in the field.
But Broad insists England's struggles in those conditions leave them better equipped than the Proteas, who have yet to play a late match.
"We have got the advantage of having played few games under the lights here," he said.
"Conditions are extremely different from anything we've had before and South Africa haven't played under the lights yet.
"But we've got the experience of that. It can give us a little bit of an edge if we use it wisely."
