Lowdown on last four

AustraliaStrengths: Well, they are the world champions in every format and have a habit of winning the big matches - twice they have been threatened with eviction from the tournament, against England and Sri Lanka, and twice they have won convincingly. Matt Hayden and Adam Gilchrist bully sides with the bat up front while Brett Lee's return from injury has given them extra pace with the ball. Weaknesses: Without Ricky Ponting they will have to make do without their best batsman and their captain. Strangely they have looked disinterested at times, too. A defeat to Zimbabwe appeared to spark them into life but another loss to Pakistan suggested the Zim loss was not a one-off. In both games they looked powerless to stop the slide and perhaps, because in the past when the ball could be thrown to Glenn McGrath and he would get them out of the mire, they have forgotten how to make things happen themselves. IndiaStrengths: Momentum. And lots of it. Their victories over England and South Africa at Kingsmead have Mahendra Singh Dhoni's side buzzing. Not least because they remain at Durban with the huge Indian population making matches there feel like home. The swing of RP Singh and Sri Sreesanth under the Kingsmead lights could worry Australia when they meet in the semi. And we haven't mentioned the power-hitting of Yuvraj Singh yet. His six sixes from an over against Stuart Broad was an astonishing achievement and ensures from now on, in every one-day game he plays, points will be shaved off his top runscorer price. Weaknesses: The swing of RP Singh and Sreesanth. If the pair do not have bowling conditions to exploit then India look short of options. There must be concerns about their lower order, too. Irfan Pathan is due in at No 7 and although he has scored runs in the international game historically, it was quite a while ago. PakistanStrengths: New captain Shoaib Malik has his players pulling in the same direction. Something which the country have not been able to boast since Imran Khan's cornered tigers. They remain the only unbeaten side in the tournament. Remember they tied with India and the contest was decided on a bowl out, something which punters should ignore. Misbah, who has hit the longest six in the tournament, is a dangerous playerlower down the order. Weaknesses: Their opening partnership has been unsuccessful and they could find themselves needing to recover from quick wickets. Sure they have managed it so far but would they be so confident doing it in a semi-final or final? Probably not. Malik needs to get more energy from his players in the field. Their ground work is costing them 10-15 runs and that could be vital. New ZealandStrengths: Daniel Vettori looks to have continued from where Stephen Fleming left off with canny field placings and clever psychological ploys. Whether Vettori's claim that his side did not like the competition was a clever way of releasing pressure remains to be seen. Much of New Zealand's progress has been down to the form of Shane Bond with the ball and Craig McMillan with the bat. Vettori's spin has been important, too. Weaknesses: Their batting does not look good enough for them to lift the trophy and it was disconcerting to see Vettori batting as high as No 7 in the last match. An over-reliance on McMillan could be dangerous particularly with hitter Scott Styris strangely ineffective. Key all-rounder Jacob Oram has not looked himself since hurting a finger against England.
