Former Melbourne captain Garry Lyon has declared that star Docker Michael Walters' current form is better than that of any player in the AFL.

The 28-year-old has been a driving force behind Fremantle's dramatic rise up the ladder, averaging a career-high 21 disposals per game, while kicking 25 goals from 12 games in his 11th AFL season.

Walters has been particularly instrumental in Fremantle's current three-game win streak, gathering just under 25 disposals per game while kicking 10 goals as the club eyes its first finals berth since 2015.

He has lifted in key moments, booting the winning scores in his side's round 10 and 11 wins over Brisbane and Collingwood, respectively, while kicking two crucial goals in Saturday's pulsating final quarter to sink Port Adelaide.

Lyon said Walters' influence kept the Dockers' win streak alive.

"They were so evenly matched, you couldn’t pick it, and in the end it was Walters’ magic," Lyon said.

“There’s no one in better form than him in the competition.

"No one is playing better.”

The Dockers will be aiming for their fourth straight win when they travel to the MCG to take on the Demons on Saturday.
