The Trans-Tasman rivals Australia and New Zealand clash with each other at the iconic venue of Lord's to decide who will top the points table.
Both teams have been in exceptional form all throughout the tournament, however, it is the Black Caps who find themselves in a spot of bother plagued with insecurity regarding their position in the final four.
Their winning momentum came to a halt against Pakistan, where the New Zealand bowlers were outclassed by a splendid Babar Azam century on a lively pitch.
More importantly, it was New Zealand's batting frailties in the consistent failures of Martin Guptill, Colin Munro and Tom Latham that were exposed by some brilliant seam bowling upfront by the Pakistan new ball pair.
They would be mindful of the history between the two sides in the past at the World Cup since four years ago Michael Clarke's men defeated New Zealand at the grand finale in Melbourne.
Two weeks prior to that World Cup final, the tournament witnessed one of the best games ever when Kane Williamson thumped Pat Cummins for a straight six to seal a dramatic one-wicket victory for his side. It would be memories from the latter match that the Kiwis would be keen on reliving.
Australia's march in this World Cup has been supreme as they have prolonged their winning streak barring one hiccup against the mighty Indian line-up.
All things seem to have fallen into place for Australia at the right time and given their 64-run victory over arch-rivals England, they would be high in confidence heading into Saturday's clash.
The opening pair of Aaron Finch and David Warner has piled on runs heavily in all games as century stands seem to be the new norm for the duo.
Meanwhile, Mitchell Starc's startling pace and ability to chip away at oppositions as crucial junctures of the game makes him a potent bowler to face.
Glenn Maxwell's glimpses of brilliance have been far too brief to gain admiration.
He has always begun his innings sprightly whenever he has come out to bat during the World Cup, striking at a rapid pace before throwing away a decent start.
The repetition of a flawed mindset to batting for long indicates a troubling matter for the Australian team management, as the side has often seen the middle order squander solid platforms in most of the matches.
Maxwell desperately needs a change in approach and restraint in his batting armour to find the desired levels of success.
New Zealand's Matt Henry has perhaps been the weakest link in the bowling attack for the past four games.
He has managed to pick up only a wicket during this time and has instead leaked runs expensively, more memorably against the West Indies when Carlos Brathwaite struck 25 runs off his crucial over.
With Tim Southee warming the bench, New Zealand might be tempted to finally give their veteran player a go in this World Cup.
