Full-time: Liverpool 0-0 West Ham
- Fourth-round FA Cup replay required after Premier League rivals play out a goalless draw at Anfield
- Hosts created the better chances, but Darren Randolph made a string of strong saves to deny Joao Teixeira, Christian Benteke and Joe Allen

- West Ham lost both James Tomkins and Cheikhou Kouyate to injury before half-time
That is it from us for now after a breathless day of FA Cup fourth-round action. We will be back tomorrow to bring you more live coverage as Carlisle face Everton and Guus Hiddink's Chelsea travel to MK Dons.
We will also have the fifth round draw for you as it happens. Until then, goodnight.
Nothing to separate these two sides in the end. Liverpool perhaps created the better chances, but Randolph was on hand to keep West Ham's clean sheet intact. Yet another match to fit in for the hosts, with the replay set to be played on either the 2nd or 3rd of February.
West Ham host rock-bottom Aston Villa on Tuesday night, while Klopp's side face a tough trip to Premier League leaders Leicester.
Payet releases Cresswell down the left and his cross finds Antonio, who sends a header crashing against the foot of the post. It would not have counted anyway as the referee blows for a foul.
Three minutes of added time to play. Is there a late winner to come in this one?
You wouldn't bet on it...
Liverpool make a second change as reported Watford target Jerome Sinclair replaces Brannagan.
Strong block from Caulker to divert Antonio's shot behind after good work from O'Brien.
Cavalier goalkeeping from Mignolet as he comes out to try and punch a West Ham free-kick clear but gets nowhere near it. In the ensuing scramble, Valencia takes a tumble but there isn't even a hint of a penalty shout there.
O'Brien then slices a shot horribly from distance.
Teixeira is down and will require attention after a rather innocuous collision with Song. The Portuguese had rather botched a counter attack with an aimless pass just seconds before.
With just 10 minutes left to play, Klopp turns to his bench for the first time as former Wolves loanee Sheyi Ojo, who scored a belter in the third-round replay against Exeter, jogs on in place of Ibe.
If Benteke had opted to play in Teixeira there, then Liverpool could well be looking at a 1-0 lead. Replays also show that Obiang gave Allen a little push during his attempt at a bicycle kick, but probably not enough to concede a penalty.
Heroic goalkeeping from Randolph as he saves from Benteke after the latter was put through by Ibe. The Republic of Ireland international then smothers Allen's rebound and denies Benteke with a third save in quick succession.
After Stewart dispossesses Antonio in the middle of the pitch, Liverpool counter with numbers and Clyne produces a searching cross. Allen's ambitious attempt at a bicycle kick falls flat, but Teixeira gets a shot away that is parried by Randolph.
Bilic makes his final change of the match, with Antonio replacing Moses. 20 minutes plus stoppage time left for someone to find the winning goal.
Reid heads away a Liverpool free-kick. Stewart fires it back in on the volley but Benteke is caught unawares and the ball bounces off him and clear. A lack of anticipation from the former Aston Villa striker there.
Clyne with another searching ball that is cleared by Reid. It bobbles to Smith, whose long-range shot is high, wide and not at all handsome.
62 minutes on the clock and Randolph is tested again after Benteke finds Smith and the versatile Australian pulls the ball back for Teixeira to let fly on the half-volley. Strong save.
Looking to make amends for that wild shot, Allen combines nicely with Benteke but his attempted cross back towards the Belgian is deflected wide by Ogbonna.
Strong attacking play from Clyne as he breezes past a lackadaisical Song before pulling the ball back for Allen, who lacks composure and drives well over the top.
Lovren enters the referee's notebook after poleaxing Moses. One of the least subtle fouls you are ever likely to see from the Croatian. Ouch.
If Bilic felt West Ham should have had a penalty for Smith's first-half handball, wait until he sees a replay of that from Caulker. The QPR loanee looked to make contact twice but it was difficult for Atkinson to see through that crowd of bodies.
Liverpool may have gotten away with one there.
A well-struck free-kick from Payet creates uncertainly in the Liverpool area as Jelavic's flick on clearly strikes the arm of Caulker before Mignolet makes a low save from Reid.
At the other end, Clyne picks up possession 20 yards from goal and drills an effort that keeps rising and drifts over the crossbar.
Moses looks to make early inroads down the West Ham right but his near-post cross is too close to Mignolet and the goalkeeper can claim comfortably.
