The Red Devils announced Ronaldo's imminent return on Friday, concluding a deal with Juventus for his transfer.
The Portuguese will undergo a medical and sign his contract before Tuesday's transfer deadline.
Speaking after United's 1-0 win over Wolves on Sunday, Pogba told the club website the following about Ronaldo's signing: "Everybody knows [what he brings]. He's already a legend in this club and he's coming back, so obviously it's huge for us, for the club.
"He's going to bring his experience, his quality and obviously when he comes the level goes up.
"We're really pleased he's coming but the most important today is the win so when he comes we keep this mentality of winning, and keep winning."
