United have made two offers to Barcelona for midfielder Cesc Fabregas, for a reported £25million and £30million respectively, both of which were rejected by the Catalan club.
Scholes, who retired from action for a second time in May, added on Sky Sports News: "I don't think there's that much pressure.
"He's got a quality squad there, with already 18-20 quality players.
"Even if Sir Alex Ferguson was there he would want to sign two or three players. That's the norm every season - to improve the year after, even if you've won the league.
"I'm sure David Moyes is trying to get players - and hopefully he'll get the ones he wants."
