Michael Vaughan says England are still in a position to win the next World Cup in the West Indies in 15 months' time, despite the recent defeats in Pakistan.
"It's a difficult tour of Pakistan. Will the conditions in the West Indies be similar to that? I doubt that.
"We do need to improve in the one-day game if we're going to win the World Cup," Vaughan told BBC Radio Five Live.
"But there are some exciting players in and around the squad which should give us an opportunity to do well."
With Vaughan back at home recovering from knee surgery, England equalled the record for their worst ever defeat on Thursday, falling to Pakistan by 165 runs.
"It's an area we need to look at because we haven't won an overseas tournament for a long time," he admitted.
"But the last major tournament was the ICC [Champions] Trophy and we got to the final.
"Over the last two years there's been some good strides made in the one-day team, we played some good one-day cricket against Australia in the summer."
"I'll start full rehab on Monday and the plan is to start hitting cricket balls in the middle of January"
England won two of seven limited-overs games against their Ashes rivals, fought out a thrilling tie in the NatWest Series final at Lord's and saw one match washed out.
They have not beaten a major opponent in a series away from home since overturning India, Pakistan and West Indies in Sharjah in 1997/98.
But Vaughan's record of winning 59% of one-day matches at the helm is better than any other England skipper since Mike Gatting, who won 26 of 37 matches between 1986 and '88.
Vaughan, who was also at home to see the birth of his son Archie last week, said he is on course to be fit for England's tour of India in February.
"I went and saw the England physio a week after the operation," he added.
"I'll start full rehab on Monday and the plan is to start hitting cricket balls in the middle of January.
"So far it's all gone well but the real test is when I start twisting and turning," he added.
