The Portuguese midfielder scored both of the Reds goals, with the first coming from a free-kick in the opening stages of the game after a fumble by Villa goalkeeper Emiliano Martinez.
It was Bruno’s first United goal for over a month, with his previous strike coming during the 3-2 victory over Arsenal at the beginning of December.
With Ralf Rangnick opting to set United out in a 4-2-3-1 formation, Fernandes thrived in the no.10 position and doubled his tally midway through the second half. Villa’s Morgan Sanson gave the ball away in midfield and Fred pounced, squaring to Fernandes who fired into the roof of the net, via the crossbar.
