But Scholes hopes former team-mate Ole Gunnar Solskjaer is given time to implement his ideas and sign his desired players.
"They've had three managers now before Ole's come in and they've got to stick with someone, they have to," he told Sky Sports. "They have to give him the time, three or four transfer windows I think they need.
"About two or three weeks ago they were playing really well, playing good football and you think 'Maybe they're not too far away'.
"And then they have a spell again, a couple of injuries, a couple of big injuries and you're thinking again 'They need three or four transfer windows'.
"Hopefully Ole's the man to get the time and money to spend."
