The West Ham boss's attitude is as key to his side's success as anything.
And that just about sums up what's going right at Upton Park under the Croat this season.
Indeed, certain West Ham managers in the past - we don't need to name who - would have parked the bus against both Arsenal and Crystal Palace and probably ended up losing both games.
That the Hammers had the audacity to take on the Gunners, Liverpool and Manchester City in their own backyards is only matched by the fact they were just as determined to beat Palace.
It's no wonder, then, that West Ham are unbeaten in five away games for the first time since 2009. And it's Bilic's attitude that ensures the east London side are flying so high.
Some people settle for very little, others are happy to lose the odd game if they've registered a memorable win. Bilic, though, appears to just want to win - all the time.
