Preston duo Emil Riis and Ryan Lowe have praised Fernandez after his performance against West Brom.
The 19-year-old defender grabbed the game-winning assist against Steve Bruce's side at Deepdale as Lowe's men secured a 1-0 victory in midweek.
He was awarded the man-of-the-match award, with his individual showing leading to complements from Preston striker Riis and manager Lowe.
Speaking after Preston's win, Riis said: "It was a great cross and he's a brilliant player. He just needs to keep going."
Lowe added: "Ball slid in, Emil in the right place where I'm going to say he probably would be just outside the six-yard box in the last few weeks because he's been hungry for a goal.
"I said get yourself in the right areas and you'll find the net because we've got good players like Alvaro who can put balls on a plate for you, and he certainly did that tonight, so I'm really pleased."
