Geelong coach Mark Thompson has predicted fireworks in Sunday's much-anticipated blockbuster against St Kilda admitting on Wednesday that the AFL's two unbeaten teams don't get along.

The two teams have had an intense rivalry since both began to emerge from the wilderness simultaneously in 2003 with Thompson first suggesting, after the Cats beat the Saints in the last home-and-away round of that season, that his team had a better list than St Kilda despite popular belief to the contrary at that time.

And then when the Saints beat the Cats in the pre-season grand final of 2004, outspoken Geelong forward Paul Chapman again said publicly that he had no doubt the Cats were the better team.

Both teams just failed to reach the grand final that season but while it was the Cats that were the first of the two clubs to end a premiership drought that stretched back to the 1960s - when they won the 2007 Grand Final by a record margin in ending a barren 44-year period - the injury-riddled Saints fell by the wayside until this season.

Now both teams have won their first 13 games of the season - the first time ever two teams have been unbeaten at this stage of the AFL season - and Sunday's clash will be their first meeting since last year's qualifying final when the Cats handed St Kilda a 10-goal hiding at the MCG.

That match also ended controversially when Geelong defender Matthew Scarlett and St Kilda's favourite son Robert Harvey engaged in a war of words after the final siren with the Cats then furious when Scarlett copped the public blame for the incident considering Harvey's exalted status and his reputation as one of the game's 'Mr Nice Guys'.

Former St Kilda assistant coach Mick McGuane admitted earlier this week there was bad blood between the sides and that during his time at Moorabbin a hatred existed towards Geelong.

And Thompson admitted on Wednesday that the feeling was mutual, adding further spice to a game already being described as the biggest home-and-away match in AFL history.

"I don't think we like each other too much, that has been proven over the years," Thompson said.

"They have always been really physical games and both teams will probably end up with a few cuts and bleeds out of this match, I would say on Sunday."

And Scarlett is expecting plenty of attention personally but told Geelong's local newspaper The
