The Reds followed up Sunday's 2-0 triumph over Aston Villa with an emphatic showing against the Scottish Women's Premiership side, as part of our week-long training camp north of the border.
United went into the break with a two-goal advantage courtesy of strikes from captain Katie Zelem and Lucy Staniforth before the former doubled her tally for the evening early in the second half.
Kirsty Hanson and Leah Galton then completed the scoring late on to cap off a successful evening's work for Marc Skinner's side.
Having drawn with Liverpool earlier this month prior to that victory over Villa, Skinner's side looked to continue building up that preparation for the new Women's Super League season with a third friendly of the summer, against Rangers.
