Two of the Premier League’s in-form clubs meet at the King Power Stadium in what should be an exciting encounter, with Leicester also set to ring the changes.
“We will try to look at other players. It is a shame that Michail (Antonio) and Jelavic cannot play as they have already played in the competition and are cup-tied,” Bilic told whufc.com.
“But we will try to maintain our chances and keep the same quality on the pitch.
“If possible it will be good to rest a couple of players who played against Newcastle and Manchester City on Saturday.”
Whoever is drafted in for the Hammers faces a tough task to replicate the form shown by their squad mates so far this season.
West Ham currently sit third in the Premier League table after six games, but will be looking to avenge the home defeat suffered against the Foxes in their second fixture.
Bilic’s men lost 2-1 that day, and were it not for the slip ups against Leicester and Bournemouth at home, they would be even closer to division leaders Manchester City.
