Melbourne star Max Gawn has revealed that Carlton big man Matthew Kreuzer is the best opponent he has come up against.

It comes in a season where the league's premier ruckman has been a hot topic, with Gawn and rising Magpie Brodie Grundy leading the charge.

But don't underestimate their fellow combatants, such as Kreuzer, Stefan Martin, Todd Goldstein, Nic Naitanui, Jarrod Witts, Callum Sinclair, Paddy Ryder, Toby Nankervis and Sam Jacobs.

And while Gawn and Grundy are considered the frontrunners to be named the starting All-Australian ruckman, the gun Demon said Kreuzer is his toughest matchup.

“I talk up ruckmen a lot and people are curious as to why I do it,” Gawn told SEN Breakfast.

“I do rate a lot of people: Scott Lycett is one of the ones I do rate, Nic Naitanui and I actually haven’t played each other since 2014.

“Matthew Kreuzer is probably the one that I rate the highest.

“His work rate, he keeps you very honest and he’s added this part to his game where he can mark and kick goals, which as a ruckman, seems to be one that you’re most scared of when they go and impact the scoreboard.”

Kreuzer has played 12 games this season after being hampered with injuries and will not feature again in 2018 due to an ongoing heart condition.
