Key played in one game at the 2009 ICC World Twenty20
Kent captain Rob Key thinks England have all the right elements to win the World Cup, despite losing the one-day series in Australia.
Key has watched all the top international teams this winter during his work as a TV pundit.
He told BBC Radio Kent: "England have got the best balance out of any team going into the World Cup.
"That's how they won the World Twenty20 and I think they'll be the same in the World Cup in the 50-over competition."
Key also believes the return of wicketkeeper Matt Prior to the England one-day squad could be the final part of the jigsaw.
"I think in Indian conditions he could really thrive, so I'm really pleased that he's there," added the 31-year-old.
"Kevin Pietersen has to come good but I do like Matt Prior at the top of the order.
"It's a big move from the selectors but I think it's the right move. It might not work, but hopefully there's a good chance of a return on that investment.
"I think the wickets will be like Adelaide - a slow wicket so that's why they've picked Matt Prior for the conditions.
"You need someone who can score 100 off 50 balls and Matt Prior can do that."
