The home side were in control of the second half were helped as Laura Vetterlein was shown a second yellow for cynical foul.
A good win for United on their first appearance at old Trafford, midfielder Ella Tonne living the dream told BBC Sport:
“As a Manchester United fan it was a dream come true to play on such an amazing pitch so it was a special occasion and I’m glad we went out there and got the three points.”
Manager Casey Stoney was more concerned with her side performance than the venue:
“We weren’t good in the first half – that was probably the worst I’ve seen us in a long, long time, so I think there was definitely a case of the occasion. That’s done now. They know what it’s like.
“Players know when they are not good enough. I said [at half-time] if you want to qualify for Champions League football, you have to play at a Champions League standard and we weren’t.
“When we started playing collectively in the second half we were better.”
