England captain Alastair Cook insisted he still wanted to lead the side at the World Cup despite conceding the team's chances of triumphing at next year's tournament were "far-fetched" following another mauling by India.

The reigning world champions inflicted a humiliating nine-wicket defeat upon England in the fourth one-day international at Edgbaston on Tuesday to take an unbeatable 3-0 lead in the five-match series.

India dismissed England for just 206, a total that owed much to number seven Moeen Ali's 67.

They then coasted to victory with more than 19 overs to spare after Ajinkya Rahane, whose 106 was his maiden ODI century, and Shikhar Dhawan (97 not out) put on 183 for the first wicket.

Defeat saw England suffer a fifth loss in their last six ODI series.

England only have a diet of limited overs cricket between now and the start of the World Cup in Australia and New Zealand in February.

Exiled England batsman Kevin Pietersen commented on England's chances at the World Cup, turning to twitter to suggest that without change his adopted country would have no hope of lifting the trophy for the first time in the 40-year history of the tournament.

I actually cannot believe that SKY are saying that it's too late to make changes! So just accept we gonna lose WC! Unbelievable! — Kevin Pietersen (@KP24) September 2, 2014

Pietersen went one-step further, naming his ideal England ODI team which unsurprisingly didn't feature his former captain.

Hales, Roy, Ali, Bopara, Morgan(c), R.Clarke, Buttler, Rashid, Broad, Anderson, Finn. Name me a better ODI team for ENG pls? #EngvInd — Kevin Pietersen (@KP24) September 2, 2014

Another England Ashes hero has weighed in on the series loss - Andrew Flintoff suggesting England's dire ODI run is nothing new.

We've been rubbish in ODI's for 30 years and we've lost 3 more , big surprise ! #thatsall — andrew flintoff (@flintoff11) September 2, 2014

Former England off-spinner Graeme Swann recently urged Cook to quit one-day cricket and concentrate solely on Tests.

But Cook, whose nine on Tuesday meant he has gone 38 innings without an ODI hundred, faced similar calls to stand down as Test skipper from half a dozen former England captains earlier in the season, only to lead the team to a 3-1 series win over India.

Cook, asked if he would be England's captain at the World Cup, replied: "If I'm allowed to be, yes.

"I don't have a say on selection, but I've captained for three-and-a-half years with the goal to try to win the World Cup in Australia.

He added: "I know that seems a bit far-fetched at the moment when we're losing games of cricket, but there are a lot of really good players in that changing room.

"If we can improve at the rate we need to improve, we've got a chance."

England, beaten heavily for the third match in a row, will try to avoid further embarrassment in the series finale at Headingley on Friday.

"Maybe for a few of these guys, it's the first time it's happened that we've lost as badly as this and it's a true test of character for the whole team, really," Cook said.
