Let's check out the tale of the tape shall we...
Liverpool are unbeaten in seven league matches against West Ham (W5, D2).
The Reds scored four goals in four of those seven matches.
West Ham have won only three of their 57 top-flight away matches against Liverpool (D15, L39).
West Ham have lost three of their past four league games.
They have also lost their last four away league fixtures. They last lost five in a row between November 2013 and January 2014.
The Hammers have picked up just five points from eight Premier League matches, fewer than any other top-flight side.
West Ham have lost a league-high 19 points from a winning position this season.
Jarrod Bowen has finished on the losing team in all eight of his Premier League appearances, seven of which came for Hull City.
David Moyes is yet to win an away match against Liverpool in all competitions (D7, L8), losing the last three in a row.
West Ham full-back Ryan Fredericks is out with the shoulder injury he sustained against Manchester City in midweek, so Pablo Zabaleta is likely to step in again.
Andriy Yarmolenko remains out, with Jack Wilshere also a long-term injury absentee.
Michail Antonio has scored in four of his five Premier League appearances against Liverpool.
