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 Premier League season ever... and the future is bright too
This is now officially West Ham's best ever season in the Premier League era.
And the signs are good for the future too with the campaign also notable for the emergence of the club's youngest ever player Reece Oxford.
The supremely talented teenager made his debut with a midfield masterclass in a 2-0 win over Arsenal at the Emirates in the opening game of the season aged just 16.
He has been used sparingly since with Bilic keen to protect his young charge.
Hilarious line from co-commentator
Oxford came on for the last 10 minutes and as the towering 6ft 5in 17-year-old made his entrance it was met with a brilliant line from co-commentator and former Derby County star Dean Sturridge.
The diminutive striker-turned-pundit, who is the uncle of Liverpool and England star Daniel, was shocked at Oxford's stature up close and remarked: "Oxford is some specimen, he looks like he's been sleeping in a greenhouse."
An even more frightening prospect for opposing teams is that the young England star still has another four years of growing left in him yet!
