Fernandes has made an instant impact since his January arrival from Sporting CP.
Robson says: “No question, he's the modern day Paul Scholes.
“He's brilliant at finding little pockets of space.
“Then he's got the same vision to hit those great balls that Scholesy used to hit — and he's also got a goal in his locker."
Robson, who played over 400 times for United, also believes manager Ole Gunnar Solskjaer should be applauded for his work before the season halted.
He said: “Ole's lads were on an 11–game unbeaten run.
“You can see that he's improved the atmosphere."
