Kevin Pietersen has voiced his frustrations after England's one-day international travails increased against India.

Pietersen has become the latest former England player to bemoan the selectors' persistence with a team which has collapsed to a Royal London Series defeat with a match to spare.

By the estimation of their own coach Peter Moores, they will be "unfancied" for the World Cup in Australia and New Zealand early next year, while captain Alastair Cook admits many see the notion of winning the tournament for the first time as "far-fetched".

After India trounced England by nine wickets at Edgbaston on Wednesday, Pietersen appeared to agree about their prospects down under.

Naming no names - although Cook's position has come into question with many - he wrote on Twitter: "So let's pick the same team for SL and for the tri-series IN AUS & WC in Aus and lose.

"Then change after that! I cannot believe it!"

Former England spinner Graeme Swann has previously stated he would like to see Cook stand down from the one-day captaincy, something the skipper was significantly irked by, and he too believes England need to change their approach to the 50-over game.

"We need Alastair Cook as a confident, buoyant captain to win back the Ashes because that's what we really want to do," he told BBC Radio Five Live.

"We're not going to win this World Cup, so if that means Alastair Cook doesn't play and just get youngsters in who are brought up on one-day cricket and willing to play a very aggressive and vibrant game.

"We might not do any better in this World Cup but down the road, four years down the line, we may have the start of a team that can actually win it."
