Amorim's side recovered from their disappointing draw with lowly West Ham last week thanks to Fernandes' double and goals from Bryan Mbeumo and Mason Mount at Molineux.
A return to Europe's elite tournament is estimated to be worth at least £70 million ($93 million) to United and would allow Amorim more resources to rebuild his squad.
Gazzetta World reports that United made a "proper offer" for Barcelona's Neymar earlier this month and are ready to break any transfer and wage records to beat Manchester City to the Brazil captain.
