Manchester United moved level with leaders Liverpool after seeing off a stubborn Aston Villa at Old Trafford.
Martial headed Utd in front just before the break but Villa bounced back when Traore slotted the ball beneath De Gea.
Fernandes hit the winner for Utd from the penalty spot after Pogba was tripped inside the box.
That decision left Villa boss Dean Smith fuming. He said he thought Pogba “tripped himself”.
The win lifted Utd level with their arch rivals Liverpool with manager Ole Gunnar Solskjaer saying “We have shown we have improved a lot in a year”.
