The Hammers were emphatic 3-0 winners over West Bromwich Albion on Saturday, a result which leaves them very much in the hunt for Champions League football with three games to go.
The club narrowly missed out on a trip to Wembley after being held by a late goal against Manchester United at Old Trafford before losing 2-1 in the replay at Upton Park.
Best season since the Boys of 86
The East Londoners have now officially enjoyed their best ever Premier League season, eclipsing the points total achieved when they finished fifth under Harry Redknapp with the likes of Paolo Di Canio.
A goal difference of +17 also tells its own story given West Ham have never recorded a positive goal difference in a Premier League season.
In fact the club has not had one in the top-flight for 24 years, dating back to the infamous 1985/86 campaign where they should have won the title.
A far cry from the last days of Big Sam
It is all a far cry from the end of Sam Allardyce's tenure at the club.
Most West Ham fans will tell you Allardyce did a good job at their club, was what the Hammers needed at the time and that their relationship met a natural conclusion.
But Big Sam has a big ego and when he suggested last week that his relegation-threatened Sunderland side were a bigger club than the Hammers - as reported by the Telegraph - it was met with howls of derision back in the big smoke.
Make no mistake Sunderland are a fine football club. But West Ham have a huge, loyal, global and growing fanbase.
The club has just confirmed it will have more than 53,000 season ticket holders at the Olympic Stadium next season.
West Ham have topped Premier League attendance charts for years anyway in terms of occupied seats in relation to their 35,000 capacity.
Hammers fans' stirring riposte
So as Mark Noble lashed home a beautiful volley after another freeflowing attacking move orchestrated on the floor by the maestro that is Dimitri Payet to make it 3-0 on Saturday, they saw a chance for a measure of revenge.
"Are you watching Allardyce" and "We're West Ham United, we play on the floor" rang out for the remainder of the game.
Of course Bilic was always going to find it tough to emulate what Allardyce achieved at West Ham.
That was according to the former Bolton man himself and countless so-called experts in the media pre-season, as reported by ESPN at the time.
He was right of course Bilic hasn't matched his success... he has surpassed it.
