Graeme Swann impessed by England options ahead of one-day series

Graeme Swann believes England have "the X-factor" to become a force in one-day international cricket.

After claiming the number one Test ranking, and winning the World Twenty20 last year, England are aiming to add world domination in the 50-over game to their growing list of achievements.

Team director Andy Flower revealed his determination to master a format in which England have never truly provided a consistent threat as soon as they reached the top Test ranking following their 4-0 series win over India.

They will get an immediate test of their credentials over the next fortnight when they meet the world champions in a five-match series.

Swann is confident Flower's ambition can be realised - because England have more match winners than ever before.

The 32-year-old off-spinner believes the likes of Eoin Morgan - whose unorthodox approach has provided a unique element to England's batting - and new quick Jade Dernbach are such match-changers ahead of the first game at Chester-le-Street tomorrow.

"We've missed a certain X-factor in the past - that has cost us," Swann said.

"But now with certain players I think we are starting to get that.

"You look at blokes like Eoin Morgan and Jade Dernbach.

"They are something different, we are starting to get those match-winners with bat and ball."

While Morgan has established his class over recent seasons, Dernbach has played just six ODIs.

The 25-year-old has, however, already helped England to a series win over World Cup finalists Sri Lanka earlier in the summer.

And he further proved his ability on the international stage on Wednesday night when he claimed four for 22 - the equal-best Twenty20 figures by an England bowler - in the six-wicket win over India at Old Trafford.

Most notable was his ability to deceive batsmen with a variety of slower balls while he was trusted to bowl the late overs - rewarding skipper Stuart Broad by wiping out the India tail.

It was also reward for England's desire to place their faith in youth.

Durham's hard-hitting all-rounder Ben Stokes has also been drafted into the ODI squad, trusted to help fill the shoes of the rested Kevin Pietersen in a further indication England are looking to select match-winners.

Swann believes it is a policy that will pay off and admits he has been impressed by how quickly the young players have established themselves.

"I think the young players who have come in have done amazingly well," he said.

"While it is easier to come into a successful squad rather than an unsuccessful one, they have more than coped with the step up to international level.

"It's as if they have been there all their lives.

"That can only be good for England."
