Head-to-head
West Ham are looking to complete their first league double over United since 2006-07. They won September's reverse fixture 2-0.
Manchester United have lost only two of their 23 Premier League home matches against the Hammers (W19, D2). United manager Ole Gunnar Solskjaer played in both of those defeats.
Manchester United
Manchester United are unbeaten in their past 12 Premier League games (W8, D4). It's Ole Gunnar Solskjaer's equal-longest league sequence without defeat as United boss.
The Red Devils will move into the top four should they avoid defeat. They have not ended a full round of fixtures in the Champions League places since mid-September.
David de Gea needs one clean sheet to surpass Peter Schmeichel's Premier League club record of 112.
Marcus Rashford and Anthony Martial have scored 12 and 11 home league goals respectively this term. It is the only the third time in Premier League history that United have had two or more players reach double figures at Old Trafford.
Paul Pogba last scored at Old Trafford in United's 2-0 win over West Ham in 2018-19. He scored both goals that day.
West Ham United
West Ham are looking to win three consecutive league matches for the first time since the final three league fixtures of last season.
The Hammers have scored at least three goals in six different league matches in 2020, a joint high alongside Manchester City and Manchester United.
West Ham have dropped an unrivalled 24 points from winning positions.
David Moyes is looking to become the first ex-Manchester United boss to win a league game at Old Trafford since Dave Sexton achieved it in 1982, while manager of Coventry City.
Moyes is yet to win a league match at Old Trafford as an away manager in 12 previous attempts (D3, L9).
Michail Antonio can become the first West Ham player to score in three consecutive league matches since Marko Arnautovic in December 2017.
