Mutliple clubs have made contact with the AFL and have questioned the umpires over favourable free kicks they believe have been awarded to the Western Bulldogs, according to Channel Nine's Footy Classified.

Journalist Damian Barrett reported the news on the show on Monday night, and suggested that a number of clubs, including Sydney following the 2016 AFL Grand Final, have asked why the Dogs' numbers are so high.

The Dogs are averaging 20.2 frees for a game this season compared to just 16.6 against, and are +47 in 2017, compared to a staggering +99 last year, which included a favourable 20-8 count in the grand final.

“There’s a procession and no-one is going to say this publicly, but clubs are going to the AFL wondering why you can get some discrepancies here in these free kicks,” Barrett told Footy Classified.

"They (Sydney) feel (the grand final) was very adversely umpired against them. Hawthorn had a similar issue in the same period of that season, and I know North Melbourne has had issues too.

"There's other clubs who are asking the AFL, 'Why are the Bulldogs being umpired this way, and almost every other club being umpired differently?'"

Guest panellist and Essendon veteran Brendon Goddard asked if clubs were referring to the Dogs' fast and quick handball game that they made famous last season, and suggested for clubs to be upset about that is quite surprising.

“As a player, that was almost laughable, I thought, to try and pin a team on getting away with so much with handballs,” Goddard said.

“Then they somewhat reacted to that last year with now paying more throws and stuff. But a lot of the stuff I saw as a player was fair game.”
