The Reds have already struggled against West Ham this season, recovering from a half-time deficit to earn a 2-2 draw at Anfield in December.
Despite the latest setback, Bilic insists that there is room for the former Newcastle man - who has completed 90 minutes just nine times in the Premier League so far this season - in his long-term plans. "We need to make the decisions for him sometimes", the Liverpool boss explained at his weekly press conference.
Lucas Leiva is a doubt for the game and must be replaced by Adam Lallana in the centre of midfield, as the England worldwide has also stepped up the recovery from his injury in recent weeks. "Now we have two more players as options".
"A week ago we thought we had to win all three".
"All the teams have to play tough games and no-one wins all of them".
Klopp has revealed that Roberto Firmino and Lucas Leiva are both rated doubtful due to muscle injuries.
"We all know the gap is not that big but the gap was big enough".
"It is obviously different (moving up from the under-23s) but the first team made it so much easier because they are so good with young kids they made it normal".
"I really wanted him to play at least one more game, against Liverpool, and he really wanted it, but the surgeon said we should operate as soon as possible so there was really no way he could play another game for us". That is good. So far it's been hard because you can't start a player then have to think after 40 minutes 'so we have to change?'
"It's a little bit another muscle which he feels". We played against Crystal Palace and we lost.
Exposed centre-backs. Expect West Ham to sit deep and soak up pressure, and if Liverpool resort to swinging aimless passes into the area, the back three will mop them up all day.
He was released on a free in 2014, when he was snapped up by fellow Premier League side Liverpool.
They have only lost one of their last 10 top-flight matches in London - their 2-0 defeat at West Ham on 2 January 2016.
