Fernandes scored United's equaliser shortly before half-time before Cristiano Ronaldo gave the Red Devils a win at Old Trafford. Michael Carrick announced his decision to leave the club following his final game in charge and Ralf Rangnick has been appointed an interim coach until the end of the season.
While on his way back home from the game, Fernandes was stuck in traffic, when a football fan pulled up alongside him, and the pair shared a funny exchange.
"I don't have you in fantasy," said the supporter. "Who have you got?" Fernandes responded.
The passenger replied: “Mohamed Salah all the way, man. I’m sorry, he takes up all my money!”
Bruno said: “Ohhh, nah!” before driving off.
The passenger pleads: “You saw him yesterday! You saw him yesterday! Come on, Bruno!”
But the Portuguese magician was long gone.
Fernandes, who has scored seven goals in 26 appearances for club and country this season, said after the game: "Every win is important for us at this moment. We know that we have been through a lot of ups and downs, and it has been hard for us to come out of that.
"Today we got a great win, but we cannot stop here and be satisfied because we beat Arsenal. The next game is coming quick, so we have to put our heads on that straight away and be ready for that one."
He also paid tribute to club legend Michael Carrick, who revealed he will step down as first-team coach following a spell as caretaker manager.
"I've said to him I was really mad to be off on his first game and I tell him now at the end of this game," he continued.
"But honestly for me, Michael can be a really good manager in the future if he gets that chance. He knows how to speak, he knows a lot of football. He was one of the great players that not a lot of people talk about. For what I have seen he can be a top coach."
