Many Arsenal fans were excited at the prospects of Lacazette and Aubameyang finally starting together under the new manager. However, Unai Emery decided to play Aubameyang and start Lacazette on the bench. However, when Lacazette came on in the 55th minute, he changed the game towards Arsenal's favor. Arsenal played with a higher tempo and a more precise and successful movement. They attacked with intent and Lacazette was in the middle of them all.

Furthermore, keeping two clinical strikers up top allows more flexibility and easy rotation amongst the two. This can also lead to using decoy runs by one of the two to shift the opposition's attention. Imagine this, Lacazette drifting wide and attracting the fullback as well as the center-back of the opposite team. Whilst this goes on, Aubameyang makes a piercing diagonal run into the box free of markers. The pace of the two strikers can see the partnership thrive on counters. With clever one-twos and a quick passing game, Aubameyang and Lacazette will find themselves in front of the face of goal plenty of times. As they are two strikers who have a high conversion rate, this can lead to great success for the gunners.
