Afghanistan's English coach Andy Moles said he was "very proud" of his team after their first ever World Cup win, against Scotland in Dunedin.
Afghanistan recovered from 97-7 to overhaul 210 in the final over and deny Scotland a first World Cup win.
"I've seen some strange things down the years but that was one of the most remarkable," said former Warwickshire batsman Moles.
"The players are so passionate and have worked so hard. I'm delighted."
Batting first, Scotland slumped to 144-8, only to be taken to their highest score in the tournament by a ninth-wicket partnership of 62 between Majid Haq and Alasdair Evans.
In reply, Afghanistan lost five wickets for 12 runs before Samiullah Shenwari's 96 took them to the brink of victory and number 11 Shapoor Zadran hit the winning runs with three balls to spare.
"I told him [Shapoor] to take it to the last over, run his singles, talk to his partner and work out what your plan is going to be," said Moles, who took up his role last September.
"In the last couple of overs, the pressure switched to the Scots. What pleased me was the fighting spirit and the will to win. We discovered some great character in the group today.
"In Afghanistan I'm sure they're very excited. It's being followed closely back home and the president sent a message of support after we played Sri Lanka."
Moles, whose team play Australia in Perth next Wednesday, said his side would only get better with more match practice.
"All the Associate Member nations struggle for consistency but the more cricket we play, the more consistent we'll get," said Moles.
"I'm not pleased with the way we played today. I'm delighted with the result but we've got Australia next, then New Zealand, then England. So we've got an immense amount of work to do."
