The Hammers are experiencing what seems to be an annual glut of injuries to key players after losing star man Dimitri Payet, strike duo Enner Valencia and Diafra Sakho, key playmaker Manuel Lanzini, winger Victor Moses and now leading defender Winston Reid too.
With six first team starters wiped out all within a month it means Bilic is left in the unenviable position of relying on injury-prone striker Andy Carroll and the unfancied Nikica Jelavic up front while his midfield is completely shorn of pace and guile.
Injuries taking their toll
Although the East Londoners came away from Manchester United with a draw in a game they could easily have won last time out, Bilic's side have now gone five Premier League matches without a victory.
The injuries have definitely taken their toll on West Ham's attacking threat and many fans feel they have taken the fizz out of a season that promised so much.
But now Jack Sullivan, the son of West Ham co-owner David, has taken to Twitter in an attempt to perk up supporters who are feeling pretty miserable going into the hectic festive schedule.
'Still a bright season ahead'
In response to one fan who said he was fed up with seeing players getting injured and demanded the club bring in reinforcements in January, Sullivan said: "Completely disagree with this to be honest, still a bright season ahead!
"(We've) just hit a real hard patch."
Completely disagree with this TBH, still a bright season a head! Just hit a real hard patch. https://t.co/nmXbNH1JcP— Jack Sullivan (@jsullivanwhu) December 9, 2015
There's no getting away from the fact the Hammers could be in for a bumpy ride for the next month or so.
It is a far cry from their electric start to the season which saw the Irons sitting pretty in third after beating the likes of Arsenal, Liverpool and Manchester City on their travels and Chelsea at home.
Who knows where West Ham might have finished
While nobody at Upton Park should be feeling too down with the club sat seventh in the league, fans must feel so frustrated at seeing injuries potentially spoil what is their last ever season at their beloved Boleyn Ground.
With a fully fit squad who knows where the Hammers might have finished this season.
But if West Ham can somehow navigate the next month or so reasonably well they will be in a good position to kick on in the new year as their walking wounded start to return from their respective lay-offs.
The Hammers entertain in-form Stoke City at the Boleyn Ground on Saturday knowing a win would put them level on points with their rivals Tottenham Hotspur in fifth place.
