David Warner
vs

Wahab Riaz

If David Warner takes off, the game will be over very quickly for Pakistan. This hard hitting Aussie opener has been in red hot form and has hit 264 runs at average of 66 with a highest score of 178. While Australia would look up to him to get them off to a flier, Pakistan would like to see the back of him early in the game. To stop Warner, Pakistan's best bet is Wahab Riaz. With 14 wickets to his name, Riaz has been the spearhead of this Pakistani bowling attack and has been instrumental in turning the tide in favour of his team. He has been lethal at the death but it is his wicket taking ability in the middle overs have taken the wind out of the opposition.

Glenn Maxwell
vs

Shahid Afridi

While both have the calibre to change the game with bat and ball, the battle will be between Glenn Maxwell, the hitter and Shahid Afridi, the leg spinner. Maxwell has found his groove in this World Cup - he's hitting them big with a mind boggling strike rate of 190. He's not just playing his usual cameos but scripting match winning knocks. Listed just below Warner in the run-getters list, Maxwell is set for yet another 'Big Show' against Pakistan. To stop the mad-Max, Pakistan need their maverick showman - Afridi, the leggie! Maxwell has a notorious weakness against leg spinners. Afridi has had an insipid World Cup till now and the game against Australia could be his last ODI if Pakistan are knocked out.

Michael Clarke
vs

Misbahul
HAQ

Whatever happens in Pakistan cricket, Misbah-ul-Haq is the man to blame. Misbah is Pakistan's favourite whipping boy, yet they can't do without him - they criticise his captaincy yet need him to lead, they slam him for his 'tuk tuk' batting yet need him to stand tall among the batting collapses. Misbah-ul-Haq is Pakistan's lone ranger. Michael Clarke, though, doesn't have so much on his plate. In fact, in the ODIs, Australia can win without him. They even started the World Cup campaign with their skipper on the sidelines. However, Clarke is important for the knock outs. George Bailey does a fine stand-in job but lacks the presence of leader. For that, the Aussies need a top dog like Pup.
