Barrow believes they have the solution on the doorstep.
"Tom is a very talented young man who is heading for the top," he told the Manchester Evening News.
"I fully expect him to make his mark at Old Trafford and challenge to take up the Paul Scholes role.
"He is good enough and he's a bit special. United have a fine player and a fine young man returning to their ranks.
"Tom has made incredible progress and he's going to get better in my view.
"Nothing is a problem for him.
"He's got the ability and he's certainly got the application.
"You couldn't meet a nicer lad. He's been a loan player who's given his heart and soul to Wigan.
"United may well spend big to replace a wonderful player like Scholes but Tom will definitely feature at some point now he is back at Old Trafford.
"Is he a better player since joining us? That's an understatement - he's given 100 per cent, he has oozed quality.
"I wish he was staying but you can see he's one of those United lads who is going to be very special."
