New Zealand captain Stephen Fleming says that there are no clear favourites in the World Cup, and all the top teams will fancy themselves winning the coveted trophy.Fleming believes that the recent wins against Australia have been a big confidence booster for his side but the poor show in the warm-up games have also pointed out the flaws that they need to iron out."There are no clear favourites, I feel it's anyone's game," Fleming said."I feel we should have made the finals of the Commonwealth Bank series ahead of England; but we got massive confidence from our wins against Australia. Now again, we have struggled in the practice games so a week can prove to be a long time in international cricket," he said.According to Fleming, good captaincy could be a vital component in a side's campaign in the tournament."It's important how you captain, the balance you achieve in your style, how early you are able to adapt and understand the conditions. A captain's input could be vital," he said.Fleming believes the manner of loss or a win could give a side enough indications on how to prepare for the future games."Style of losses and wins give a side an idea on the areas to look to improve," he said.
