Cook eyes one-day improvement

Alastair Cook enters Wednesday's must-win fourth one-day international against New Zealand admitting he is still a long way from becoming the finished article as a limited-overs player for England.

The Essex left-hander, who has developed impressively as an opener in the shortened format of the game since making his debut nearly two years ago, said: "The ideal role model is someone like Matthew Hayden, who has pretty much got the all-round game - he can hit sixes and he can hit singles to rotate the strike as well.

"If I'm looking at someone to follow, he would be where I'd like to end up at some stage. It is not going to happen after one day or one series, but work over time can get me somewhere close to it."
