England can still win the World Cup despite its ongoing lack of consistency in the limited overs game.
Paul Collingwood says that despite the latest problems, failing to qualify for the semi-finals of the Champions Trophy in India, England can still mount a serious challenge for the World Cup.
He told BBC Sport: "We have to forget about the last 12 months, but the potential is there."
England's only win at the Champions Trophy was the dead match against the West Indies.
"It's a massive positive to finish like that, but it's also frustrating for us," he said.
"We keep teasing ourselves in one-day cricket.
"We know how good we can be but we don't put the performances in consistently," he said.
A continuation of how the team has played in the last 12 months would mean it would be nowhere near the mark at the World Cup, he said.
"But if you look at Kevin Pietersen, Freddie Flintoff, Marcus Trescothick, not many teams will fancy coming up against a batting line-up like that.
"We're confident we can do it," he said.
England's first game at the tournament is against New Zealand.
England's chairman of selectors David Graveney said England would be doing everything possible before the World Cup.
"Nobody is sitting on their hands and not rating one-day cricket as important as Test match cricket.
"We treat one-day cricket with the same intensity and attention to detail as we do Test cricket," he said.
