GEELONG captain Joel Selwood has predicted his brother Scott will get the job of trying to negate the influence of Adelaide's "fire-starter" Rory Sloane in Friday night's clash at Simonds Stadium.

Sloane, averaging 27 disposals a game in 2017, has had limited impact when subjected to a hard tag at times this season.

Speaking on RSN927 radio on Tuesday morning, Selwood said his hard-tackling sibling would spend time manning the Crows' star playmaker.

"I think he'll have him at stages throughout the game, Scotty; (Sloane) has been in some great form this year," Selwood said.

"I did watch bits of him on the weekend and he was getting sat on heavily early and still finding a way.

"He is the fire-starter for them, he's been playing some great footy, and we will need to make sure we calm his influence."

The match-up looms as a fierce one, as Sloane and Selwood are two of the AFL's best tacklers.

The Adelaide vice-captain is the competition's most prolific tackler this season with 91, while Selwood has laid a remarkable 34 tackles in his two games back from a pre-season toe injury.

In high praise, the Cats skipper compared his brother's impact on the side to that of what premiership captain Cameron Ling provided during the club's flag winning seasons of the past decade.

"(Scott) is a tackling machine, but he'd probably like to win a bit more half contests himself," Selwood said.

"He has been doing a good job the last couple of weeks, since he's had a job to do and he's done it really well.

"It's nice to have that pillar in there – a bit like Lingy back in the day – to have that guy that goes someone."
