But fans will be left wondering where they might have been had Bilic not been rocked by a glut of injuries to key first team players over the last three months.
At one stage the East Londoners were without hero Dimitri Payet, key playmaker Manuel Lanzini, strikers Enner Valencia, Diafra Sakho and Andy Carroll, winger Victor Moses and star defender Winston Reid.
January signings Sam Byram and Emmanuel Emenike missed the 2-0 win over Aston Villa on Tuesday night through injury and an issue over international clearance respectively while defender Angelo Ogbonna was out through illness.
While the likes of Payet, Valencia, Moses and Reid are fit again the Hammers are still missing Carroll, Lanzini and Sakho.
The trio were all scheduled for mid-February comebacks while Nikica Jelavic is set to leave for a move to China.
But the Hammers have received a massive boost with news from the treatment room and board room ahead of the crunch league clash at in-form Southampton on Saturday and the FA Cup replay against Liverpool on Tuesday.
That's because no fewer than five previously unavailable players could be ready to freshen up Bilic's side at a crucial time.
According to West Ham's head of medical and sports science Stijn Vandenbroucke's latest update on the club's official website Carroll, Emenike and Ogbonna are all ready to face Ronald Koeman's side at St Mary's.
And as if that wasn't good news enough Lanzini and star striker Sakho could return for the vital cup clash against Liverpool.
'We are very happy'
"New signing Emmanuel Emenike will also join up with the squad for his first training session and will be available for Saturday’s game at Southampton having obtained his work permit.
"We are very happy to have him in our squad.
"Angelo Ogbonna missed the game against Aston Villa through illness. We hope to recover him in time for the Southampton game.
"Diafra Sakho and Manuel Lanzini are in the final stages of their rehab and are knocking on the door to train with the first-team."
