AN IRRESISTIBLE force meets an immovable object next Saturday night when Fremantle hosts the Sydney Swans and Ross Lyon has his eyes firmly fixed on the clash already.

Lyon wasted little time in shelving the Dockers' comfortable 30-point win over West Coast on Sunday.

The Dockers slaughtered West Coast in a clinical first-half display but Lyon said post-match that he had already moved on from the win.

"We've already spoken about Sydney, and they've already spoken about us," Lyon said.

"It's going to be one of the games of the round. 

"Everything we did today we'd like to do (again). But we know West Coast was a little bit off early, and we were right on.

"But I think two equal forces will meet next week. We saw what (the Swans) did to Port Adelaide (in Adelaide). They'll bring real heat for a long period of time.

"We'd like to keep the spread of goalkickers going. We're going to need them. But it's going to become a bigger challenge." 

Five talking points: West Coast v Fremantle

Lyon said the quality of the Swans' midfield would be a test for his side despite the irresistible form the Dockers' on-ballers are in at the moment. 

Even with relatively quiet games from David Mundy (21 disposals) and Michael Barlow (18), Lachie Neale (42 and three goals), Stephen Hill (30 and three), Nat Fyfe (31) and Danyle Pearce (27 and one) combined for 130 disposals, 23 clearances, 22 inside 50s and seven goals. 

Lyon said he was very pleased with his midfield's output and the spread of goalkickers across his team.

"The best teams run deep through the midfield," Lyon said.  

"Every team wants a spread of goalkickers. 

"It certainly helps the burden. But one swallow doesn't make a summer. 

"We've been improving our capabilities to spread the load."

The Dockers did ease off the accelerator in the last quarter to concede six goals to the Eagles.

The margin did not reflect the dominance of the Dockers' victory but, intriguingly, Lyon said no one was happier than him to see his side fade in the last quarter. 

"There's no happier person than the coach about the last quarter," Lyon said. 

"We hear the message. They came home strong, and we didn't play very well in the last quarter. So we'll acknowledge that. It's a really sharp reminder for us. So I'm the happiest person in the room at the moment. 

"We're under no illusions. We're no juggernaut. We're a hard working, blue-collar team. When we do things well, we're capable. But if we back off, we'll get hurt quickly."

The Dockers will only have a six-day break before fronting up to face the Swans on Anzac Day but Lyon said his team had a clean bill of health and had no excuses ahead of one of the most anticipated matches of the season.
