Geelong lead AFL betting for the ultimate grand final

AFL betting fans have a tough choice for the weekend's grand final as Geelong and St Kilda gear up for a clash of styles.

Geelong sealed their place in Saturday's MCG showdown with a 120 to 47 victory over Collingwood at the weekend.

Betfair has St Kilda down as the outsiders for the final showdown, on 2.52, while Geelong are installed on 1.64 with the same bookmaker after their crunching win over the 'Pies.

According to reports, both teams are likely to keep changes to a minimum, and both have few injury worries as they head to the season finale.

The tie as a whole was given a boost on Monday when the AFL tribunal elected not to put any charges on either side from the preliminary finals.

Analysts are already poring over the fine details to find clues as to who will lift the 2009 Premiership.

Writing for the Sydney Morning Herald, Richard Hinds says: "Trying to find the gap between St Kilda and Geelong is like trying to discern the gap between two grains of sand - even under the most powerful microscope, you are hard put to make it out."

St Kilda are known for a tight zone defence, while Geelong have a more swashbuckling image.
