Fernandes has been an integral part of Ole Gunnar Solskjaer's side since making the move to Old Trafford last January and he has been directly involved in 52% of United's Premier League goals since his debut.
Scholes is a big fan of the midfielder and told United's official website : "What he's doing is phenomenal, really.
"I think if you look, since he's been [here], United would be top of the league if they won their game in hand, with more points than Liverpool, which is strange to think really because they've had such a bad start to the season.
"Well, you thought it was a bad start to the season, but they're still right in there and I think they can only get better. The numbers he's produced are just ridiculous, let's hope he carries on."
Scholes added: "He's better than me. He's different to me. He scores more goals than me, he creates more goals than me. I'd like to play with him, probably behind him would be alright.
"But no, he's been sensational, a big difference. I think before he came to the team, United could hardly create a chance with some of the stuff they were playing, but now they look like they can score three, four or five goals every game.
