Scholes, who has been a staunch critic of Louis van Gaal's methods, admitted that United showed real attacking intent in their 3-3 draw with Newcastle United on Tuesday night.
The display was an improvement on recent outings for the Red Devils but Scholes insists van Gaal's men are still nowhere good enough to win this season's premiership.
"They looked a real threat, there was an intent to score goals," Scholes told BT Sport.
"When you look at their upcoming fixtures, every fixture feels like a tricky fixture. You're not sure what United you're going to get and at home they've struggled really.
"The last eight results have not been good enough, obviously. The win against Swansea was good, the draw against Chelsea was good, you probably accept.
"And you have to remember you're playing against a team that's second from bottom with their confidence really low and they've not won that game as well.
"Is it a team that can go on to win the league? I don't think so at the minute.
"Top four is a definite possibility. They should be good enough for the top four without a shadow of a doubt."
