The Hammers haven't let dodgy decisions affect their storming start to the season.
The Croatian feels that the significance given to the so-called bigger sides by the press, means that poor decisions against them are magnified – making referees more likely to rule in their favour.
"The big clubs are always getting decisions. I don't think it is deliberate," said Bilic.
"But it is the same in Croatia, Spain, Germany and Turkey. I'm sure it is not deliberate but the biggest clubs also have the biggest press.
"If they are not given a penalty it is a big scandal but if a small club is not given one it is shown at midnight and not prime time. That's why they are big clubs."
The issue has long been debated in football, and it’s hard to deny fortune lies with the big boys when it comes to refereeing decisions over the course of the season.
Despite being seemingly disadvantaged, Bilic and his side have been in inspired form this season and find themselves sat in third place in the Premier League table after six games.
The scalps of three of the league’s biggest clubs have been taken along the way, with nine of the Hammers' 12 points coming away to Arsenal, Liverpool and Manchester City.
West Ham’s underdog status has so far worked in their favour and Bilic will be more than happy to continue flying under the radar - without the added scrutiny of being a ‘big club’ – if results of this kind can be maintained.
