The Gabon striker has struggled for goals this season, but found the back of the net to equalise against the Saints in a 1-1 home draw.
While the Gunners did not claim all three points, they did end their run of losses.
Asked about the goal, Aubameyang told reporters post-game: "Tonight is not about my goal or me, it's about the team.
"As I said, we need points so it doesn't matter if I scored.
"For the moment, the most important thing to do is win games and get points."
