With his team trailing 1-0 at the break, Fernandes came off the bench and inspired a magnificent turnaround as the visitors ultimately triumphed 3-1.
Including the assist for Paul Pogba's equaliser, the Portuguese created eight chances, the most in a 45-minute Premier League appearance for almost 13 years.
That contribution made Fernandes an automatic pick as the competition's all-time leading goalscorer, Alan Shearer, chose his Team of the Week.
"Made big saves, especially sticking out a foot to deny Gylfi Sigurdsson a late winner."
"Started the turnaround with his low cross for Olivier Giroud. His deliveries are a dream for a centre-forward."
"He was everywhere, forcing an own goal from the right wing, scoring brilliantly from the left and netting another in the middle."
"A leader and a warrior, he protected his defence brilliantly again."
"Set up the opening goal with a great through-ball and then coolly converted his penalty."
"While Pogba scored a great goal, Fernandes changed the match, coming on at half-time and creating an unbelievable eight chances."
"His two goals provided a welcome reminder of what he can do."
"Assisted Son Heung-min’s goal and then produced an emphatic finish of his own, while also helping out in his own box."
"Few players could have scored the goal he did. He is just so clinical."
