Sam Allardyce's side have not been able to build on that excellent draw at Anfield on Boxing Day. They have only managed one win since, and have shipped too many goals to have any chance in most games they have played.
Last week, they were outclassed 2-0 by Tottenham Hotspur in North London. With Harry Kane back in their starting lineup for that one, Spurs looked in full control of the contest.
The England captain and Son Heung-min each scored a goal to condemn West Brom to their 15th loss of the season.
Manchester United, on the other hand, have been a bit shaky since losing to Sheffield United a few weeks ago.
The Red Devils remain second in the league table, but are five points behind city rivals Manchester City, who have a game in hand.
United delivered a comeback from that disappointing 3-3 draw against Everton last weekend with a 1-0 win over West Ham United in the FA Cup fifth round.
However, Solskjaer will be keen for his side to build consistency and deliver better defensive performances than they did in that game against Everton.
