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 last week.
A 3-1 win over Watford last time out kept the Hammers on course for European football next season, a quest they will resume against West Bromwich Albion this weekend.
Classy midfielder Pedro Obiang has impressed everytime he has stepped onto the pitch in a claret and blue shirt.
The Spaniard is a throwback to a young Michael Carrick and West Ham tend to win when he plays. Calm in possession and a fantastic passer of the ball, Obiang was signed by Hammers talent spotter Tony Henry before Bilic's arrival.
The Croatian has only used him sparingly this season with many of his 22 appearances coming as a sub.
Hammers fans feel the 23-year-old should have played more and his lack of game time has led to speculation he could return to Serie A with Napoli although the club are believed to be keen to retain his services.
Republic of Ireland goalkeeper Darren Randolph was doubted by fans and pundits when he had to fill in for number one Adrian after his sending off in the second game of the season.
But the former Charlton shot stopper proved he was more than up to the task and like Obiang has impressed everytime he has taken to the field this season.
He produced some fantastic performances in the league during Adrian's absence and during his run in the side in the FA Cup.
When Adrian hit a spell of indifferent form recently many fans felt Randolph should replace him.
But Bilic kept faith with his number one, and was repaid when he saved a penalty against Watford last time out.
So good have Randolph's performances been for club and country - he helped set up the goal which saw the Republic qualify for Euro 2016 - that there are sure to be a number of clubs looking to tempt him away with first team football next season.
