Leah Galton was part of a United side that went on a lap of appreciation after the final whistle.
The songs in Galton's honour underlined her status at a club she will leave in the summer.
Along with Ella Toone and Millie Turner, Galton is one of three remaining members of United's first professional squad in 2018.
Despite being plagued by a back problem all season, she was able to come on for the final 10 minutes to an enthusiastic ovation.
However, her exit feels symbolic as United head into an uncertain summer at the end of a season that promised so much but, since the memorable Champions League triumph over Atletico Madrid, has petered out badly.
Skinner has tried to quell the talk about his future but after such a disappointing end to the campaign, he knows improvement will be required if United are just to stand still.
In addition to the three teams destined to finish above them, the club also know a number of the clubs below are snapping at their heels, Brighton being one of them.
The Seagulls are in a wonderful place.
Indeed, after coming so close to one slice of history, next week they will attempt to carve out a more significant one by reaching the FA Cup final for the first time.
After shocking Arsenal in the FA Cup quarter-finals they then stunned Manchester City to delay the champions-elect's title celebrations.
In addition, they have announced plans for a new 10,000-capacity purpose-built women's stadium next to their main ground at Falmer.
