Afghanistan believe they've still "got a scare" left in them ahead of their World Cup finale against England in Sydney on Friday.
Both sides go into the match with the same number of points after each having a win over Scotland.
Afghanistan's one-wicket over Scotland was the latest chapter in a remarkable rise that's taken them from the lowest rung of international cricket to the game's showpiece tournament in barely seven years,
England have suffered losses to New Zealand, Australia, Sri Lanka and Bangaldesh and now Afghanistan coach Andy Moles wants his side to pile on the misery.
"They (England) are not in the best of nick at the moment and we still believe that, if at the top of the order with the bat especially, we just need to show a bit more composure, we've still got a scare in us," said Moles.
"If we can play well and hold our nerve on Friday, and we need to be at our very, very best and we need England not to be at their best, we can get a shock," the former Warwickshire batsman added.
England looked anxious during a run-chase that ended with them all out for 260 trying to overhaul Bangladesh's 275 for seven.
By contrast, Moles said his players' unrestrained approach held the key to an upset.
"I think it's just the freedom of play. It's one thing I've tried to allow to happen and enhance.. they must play the Afghan way."
Victory in Afghanistan's first one-day international against England would be a feather in Moles's cap.
"I suppose inevitably it is," he said.
"Coaching is a thankless task at times and when things don't go well it is a lonely place to be," he said in an acknowledgement of the criticism engulfing England counterpart Peter Moores.
Afghanistan suffered a World Cup record 275-run defeat by Australia last week but England have no fast bowlers to compare with Mitchell Starc and Mitchell Johnson, who shared six wickets between them in Perth.
England will be without opening batsman Moeen Ali (side strain) and all-rounder Chris Woakes (foot) after the pair injured themselves in Adelaide.
Recent experience shows just how dangerous the last match of a tournament can be for an already knocked-out England side.
England, in a display of rank incompetence even by their standards, were dismissed for just 88 in a 45-run World Twenty20 hammering by the Netherlands in Chittagong last year -- a defeat that cost Ashley Giles his position as England's limited overs coach
Now Afghanistan are looking to follow in the footsteps of their fellow non-Test nation, albeit in a different format.
