The Brazilian has spent far too long on the sidelines during his Red Devils career but the precise through ball to set Wayne Rooney up for his 10th goal of the campaign was a further reminder of his capabilities.
"I am still not 100%," said Anderson, who was making only his second appearance since spending six weeks on the sidelines with a hamstring strain.
"Maybe I need one or two more games, then I think I'll be okay.
"It's important for me to not have any more injuries because every time I think things are fine I end up having to stay out for a month and train hard to get back again.
"Now we are just taking it slowly and trying to ensure there are no problems."
