England spinner Graeme Swann believes that England will have to beat India not only in the ODI series at home but away as well if they want to be counted amongst the best limited-overs teams.
Swann said England will need to win in the return series in India next month.
"Our official ranking is five and I don't think we can argue with that," Swann was quoted as saying in Sky Sports News.
"We have shown some improvement recently but we have to continue that if we want to be one of the best teams. We have to beat teams like India, not just in this series, but when we go away to play them as well."
Swann believes ODI captain Alastair Cook has proved his critics wrong after his match-winning innings at the Rose Bowl on Tuesday.
"He's just letting his bat do the talking," Swann said. "It is very good for Cooky. He works very hard on his game. No one works harder on his game, although Kevin Pietersen might tell you differently. It is brilliant that it is paying off for him. He was written off - he's even hitting sixes these days. So you never know, hell might freeze over."
