The tie remains on knife-edge ahead of Wednesday's contest after the two sides played out a 1-1 draw at Leigh Sports Village last week.
Match preview
Having reached the quarter-finals of the Champions League in each of the last five seasons, PSG are favourites to advance from the qualifying tie, especially with home advantage in their favour for the second leg.
The Parisians would have been content with the first-leg result despite giving up the lead after Tabita Chawinga had opened the scoring in the 54th minute.
PSG were back in action at the weekend for a home league fixture against Reims, but they were unable to complete the contest due to fireworks being launched onto the pitch from outside the stadium.
The decision was made to abandon Saturday's fixture fixture, which was goalless before the contest was stopped in the 46th minute.
Jocelyn Precheur's side will now refocus for their midweek European clash, where they will look to end their four-game winless run in Champions League encounters.
In contrast to their hosts, Man United are competing in their first-ever Women's Champions League campaign after finishing in second place in the Women's Super League last season.
The Red Devils looked to be heading to defeat in their maiden European outing, before Melvine Malard came off the bench to cancel out Chawinga's opener, ensuring the English side will travel to Paris on level terms.
They were involved in another 1-1 draw in Sunday's home meeting with Leicester City, which would have frustrated Man United boss Marc Skinner.
Although they have avoided defeat in all four games this season, the Red Devils have now played out three consecutive draws in all competitions.
After conceding the first goal in each of their opening four matches, Man United will be determined to make a positive start to Wednesday's encounter.
