The 23-year-old, who is approaching the end of his third spell at Molineux on loan from Chelsea, believes staying up would eclipse being part of the side which won the Championship two seasons ago.
But Mancienne has no idea whether he will return next season. When asked if he would like to stay at Wolves, Mancienne said: "I've got to go back to Chelsea.
"But beyond that, I can't say what's going to happen because I don't know myself. All I know is staying up would definitely top winning promotion because of the pressure on us.
"Everyone was expecting us to go down but hopefully we can prove them all wrong. We're out of the bottom three but I don't think we've got enough points to be safe.
"We've got to take what we did on Sunday (against West Brom) into the next game and keep going. We can't take our foot off the pedal."
