Sancho came off the bench for United to make his first competitive appearance since singing from Borussia Dortmund this summer.
The 21-year-old took to Instagram to reflect on his first minutes as a Red Devil.
Sancho posted an image of himself coming onto the field, along with the caption " First minutes as a Red, what a start to the season. PP x BF link up".
He also added an emoji of a frozen face.
