#2 Pierre-Emerick Aubameyang
The Gabonese striker has proven once again that he deserves to start every game for the Gunners. Unai Emery has sometimes opted to play with a lone striker, dropping either Lacazette or Aubameyang. However, the former Dortmund man has been the club's key player this season as he has now scored 25 goals in all competitions for Arsenal.
Nevertheless, he delivered his best performance by playing in his natural role this time and successfully terrorized Valencia's backline with his bursting pace. Once again, he forged a deadly partnership with Lacazette up front and was directly involved in two of the Gunners' three goals.
First, he unselfishly sent a brilliant delivery to assist Lacazette's first goal even though he was in a position when he could have tried for goal himself. Second, he registered a goal by finishing Sead Kolasinac's sublime cross at the 90th minute to seal the game for the Gunners.
