The visitors, meanwhile, will be looking to maintain their 100% record after winning their opening two Women's Super League matches.
Match preview
Man United boss Marc Skinner will be content with his side's start to the season, having seen his team win one and drawn two of their opening three matches across all competitions.
After coming from behind to beat Aston Villa in their league opener, the Red Devils were on course to make it two wins in two when they took a 2-1 lead against Arsenal thanks to strikes from Leah Galton and Melvine Malard.
The Red Devils were back in action in midweek for the first leg of their Champions League qualifying tie against French giants Paris Saint-Germain.
They played out a 1-1 draw in their first-ever Women's Champions League match after Malard came off the bench to cancel out Tabitha Chawinga's 53rd-minute opener.
Man United will have one eye on Wednesday's second leg in Paris, their initial priority will be to extend their unbeaten run in the WSL to 10 matches.
After being involved in a relegation fight in both of the last two seasons, Leicester will be setting their aspirations a little higher this term following their positive start to the campaign.
The Foxes kicked off the season with a 4-2 win over newly-promoted Bristol City, before they claimed a narrow 1-0 victory over Everton last weekend thanks to Lena Petermann's second-half strike.
That result ensured Leicester finished matchday two as just one of two teams - alongside Liverpool - that are yet to drop points this season.
Willie Kirk's side continued their fine start to the season in midweek after goals from Aimee Palmer and Hannah Cain guided Leicester to a 2-1 win over Liverpool in the League Cup.
Leicester will now turn their attention back to WSL matters, and they will be looking to pick up their first WSL point against Man United, after losing their previous four head-to-head meetings in the competition.
