This is going to be another important clash. If Australia beat Pakistan, they will make it to the semis as being the leaders in the group, while Pakistan will take the second spot. Things will complicate if Pakistan beat Australia and India down West Indies. Then, the margins of the wins will decide which team joins Pakistan in the last four. The greenshirts are assured of a place in the semis but shouldn't be taking the game lightly as winning against Australia will give them a big boost. Pakistan needs to better their bowling effort. Umar Gul was disappointing in the last game and he has much more talent than what he is currently displaying. Pakistan might be tempted at resting him for this game and bringing in Mohammad Asif which will give a new dimension to the bowling. Resting Mohammad Aamer and bringing in Rao Iftikhar also won't be a bad idea. The batting needs to keep up the good work with the openers showing some more maturity in their shot selection. The other thing that Younis Khan and his men would like to change is their recent record against Australia which has been pretty poor. Australia just need one point from this game to move ahead but they will be going for an all out win and won't be leaving anything to chance. In batting Australia needs some improvement at the top with Shane Watson being out for two consecutive ducks. Ricky Ponting's form looks ominous and he will definitely try and attack the Pakistani bowlers and this is where the spinners will come into play. Australia also lack in the back up bowlers - an area which Pakistan batsmen can exploit. However Brett Lee and Mitchell Johnson are in good rhythm and will be the ones to look out for. If Pakistan plan well and apply well there is no reason why they can't beat Australia. In this case it's more of a mental barrier which they need to overcome. Australians will be fighting it hard so fans can expect an exciting contest today. Players to look out for Ricky Ponting is in fine form in the tournament scoring 79 and 65 in the two games he has played. Ponting enjoys a good ODI record against Pakistan and will be more than eager to bat well today against a quality Pakistan bowling attack to see his team through to the next round. As they say form is temporary class is permanent. And Mohammad Yousuf gave a perfect example of this when he shepherded Pakistan's innings through against India. Yousuf will be expected to play a similar role against a potent Australian bowling today given his better technique and loads of experience. Head to head & Conditions Australia enjoy a superior ODI record against Pakistan. They have won 46 out of the 80 ODIs played between the two sides while Pakistan have won only 29. In recent form Australia have won three out of their last five games while Pakistan have won four out of their last five. Pitch at Centurion will be conducive for batting given the fact it's a day game, however spinners can play a role due to the dry surface. India v West Indies, Wanderers Indians have got their work cut out in terms of qualification for semi-finals is concerned. India needs to win and win big today against West Indies - a team which has already been eliminated from the semi-finals race. Even if India wins today they will have to pray that Pakistan beat Australia and that too by a reasonable margin which will enable India to move ahead on net run rate. India's chances of semi-final qualification have suffered badly with the washout against Australia and the overall picture looks pretty bleak for them. MS Dhoni needs to inspire his charges for today's game. West Indies despite being under strength have fought it out in their two games against Pakistan and Australia. The West Indies batting batted bravely against Australia in the last game and they can surely trouble an out of sort Indian bowling line. If the West Indies batsmen manage to do the basics well they can indeed do well against India whose bowlers clearly look short of match practice. While in bowling West Indies have to one or two capable bowlers like Kemar Roach and Gavin Tonge who can test the Indian batsmen with their pace and movement. India needs to do something about their bowling as it has been fairly disappointing so far. Despite playing five bowlers against Australia nothing much changed for them and they went for runs. Only Ashish Nehra has bowled with some consistency and poor form of Harbhajan Singh and Ishant Sharma has reflected badly on their performance. Batting will also have to deliver as they have failed to live up to their high profile billing of being one of the best in business. Midway through the game India will come to know as to what they need to do as Pakistan and Australia will be playing a day game. So all in all the game might not be very tough for India but their qualification chances of semi-final surely hang with a thread. Players to look out for Ashish Nehra has been bowling well so far for India in the tournament. After taking four wickets against Pakistan he took another wicket against Australia. He certainly has the talent and will challenge the inexperienced West Indian batting line with his left arm seam bowling. Kemar Roach is nippy sort of a bowlers who caught everyone's eye in the game against Australia with his extra pace. He was clocked bowling at more than 150 kmph which is seriously quick. Head to head & Conditions In the 94 ODI games played between the two sides West Indies have a clear upper hand with 54 wins in comparison to 37 for India. In the recent overall games India have won two of their last five ODI games while West Indies haven't won any of their last five games. The pitch is expected to be a pacy one which can test the batsmen. Expected line-ups India: Gambhir, Tendulkar, Dravid, Raina, Dhoni, Kohli, Harbhajan, Mishra, Nehra, Sharma, Kumar. West Indies: Smith, Fletcher, Richards, Dowlin, Reifer, Walton, Bernard, Sammy, Miller, Roach, Tonge.
