Top coach Bob Woolmer has predicted more shock results at the World Cup following Canada's surprise win over Bangladesh.
Woolmer was appointed as a High Performance advisor by the International Cricket Council with the job of helping Kenya, Canada, Namibia and Holland compete against senior sides.
And he was delighted by Canada's performance at Durban, where they outplayed Bangladesh by 60 runs.
"I don't think we have scratched the surface, in terms of what we can achieve with amateur cricketers.
"The important thing is that they are competing and not just being totally run over."
He added: "We are trying to put structures in place to give the smaller countries a better chance and get them to practise hard.
"It's also about helping with video analysis and equipment like bowling machines.
"They won't have had that before, they would have bumbled through as they always had before - it proves they work."
Woolmer played Test cricket for England during his playing career.
He later established his coaching reputation by working with the South African national side from 1994 to 1999 before taking a job in English county cricket with Edgbaston.
Woolmer was instrumental in Namibia's recruitment of Warwickshire all-rounder Dougie Brown to join their coaching team for the tournament.
"The team that have really improved are the Namibians, even though they had a bit of a bad day against Zimbabwe.
"It's fantastic to see," Woolmer commented."
