The hosts are sitting in fifth position in the WSL table, with just goal difference separating them from their fourth-placed opponents.
Match preview
The Reds will be in a buoyant mood after they produced a superb display to beat reigning WSL champions Chelsea in Wednesday's home league clash.
Goals from Sophie Roman Haug and Gemma Bonner gave Liverpool a two-goal lead, before the game produced three quickfire goals to leave the score at three goals apiece ahead of the closing stages.
Bonner proved to be Liverpool's hero, heading home her second goal of the game in the 92nd minute to snatch all three points and dent her former side's title hopes.
Having picked up 35 points from 20 matches, the Reds have the chance to finish in fourth place in the top flight for the first time since
With Liverpool targeting a win that would move them into fourth spot, they will look to draw inspiration from the fact they claimed a 2-1 victory in December's reverse fixture.
Man United are set to fall short of last season's second-place finish after experiencing an underwhelming WSL campaign.
Despite failing to meet their expectations in the league, the Red Devils could still claim their first major trophy in next Sunday's FA Cup final against Tottenham Hotspur.
Marc Skinner's side are hoping to carry momentum into the final after putting together a four-game unbeaten run in all competitions.
In their most recent outing against Leicester City, Ella Toone produced an unstoppable long-range effort to score an 83rd-minute winner, clinching her side a narrow 1-0 victory.
The Red Devils have won both of their last two competitive away games against Liverpool, including a 1-0 win in November's League Cup fixture.
