Australia coach John Buchanan wants his side to expose England's failings which he believes have not been addressed convincingly despite the teams sharing the NatWest Series by virtue of Saturday's tie at Lord's.

Buchanan gave a stinging riposte to opposite number Duncan Fletcher noting the Australians' uncertainty in the field during the last-ball thriller, the decision to shield Glenn McGrath from the strike and the domination of the opposition batsmen by Andrew Flintoff and Steve Harmison.

As well as slating England's fielding - generally "lumbering" - Buchanan believes the top order is delicate with Marcus Trescothick, Andrew Strauss and captain Michael Vaughan struggling against Australia's attack.

"We certainly do see areas to exploit, that is one thing we have come away from that series with," Buchanan said yesterday at Headingley where the two teams embark on a three-match one-day series tomorrow before five Test matches in which England will attempt to regain the Ashes.

"There are a lot of areas we believe - and probably haven't changed our thinking since seeing England - we can exploit. We are confident on that, it is just about us delivering on our skills."

While Trescothick's troubles against the world's best team are well known, Strauss has struggled. Vaughan's record is better against Australia than any other country.

Buchanan sees a pattern in the dismissals of the trio and said: "I think every batsman - or every bowler for that matter - is a threat every game, that is why they are international-quality players. The quality of good players is that they can combat what the opposition puts in front of them and go on to play their game. But our job is still to try to make sure that in a batting sense England's top three or four players are really under the microscope." Buchanan said Paul Collingwood, Kevin Pietersen and Vikram Solanki were England's only decent fieldsmen, adding "other than that, they are quite lumbering in the field".

The NatWest Challenge format allows mid-match replacements - a batsman who can field is likely to take the place of a fast bowler once his spell is over - and Buchanan said: "England have been doing that anyway with the use of Solanki as almost a permanent sub fieldsman for them as they rotate Harmison, Flintoff, Ashley Giles and those blokes."

Meanwhile, England fast bowler Simon Jones sees reason for English optimism, saying: "We have been solid for three years but have taken an extra step up for Australia. We both know we are the two best teams in the world and there is a lot of competition and a lot of heart on display."
