The Chelsea midfielder is set for a United medical today.
Speaking on Sky Sports 1 on Wednesday evening, Neville said: "This is a number 10 who plays in a wide area, and I'm imagining that Robin van Persie and Wayne Rooney would take up the predominant roles, but he's a huge talent.
"He can spot a pass. They've lacked creativity at times Manchester United in the final third and he definitely has that.
"I think that this is a big transfer window for them. If they can pull in a big signing it would lift (executive vice-chairman) Ed Woodward, it would lift the fans and it will give everybody at the club a boost. They need that here."
