Aubameyang robbed Norwich City goalkeeper Tim Krul of the ball to register his 50th goal in the England top flight.
Mikel Arteta is convinced Arsenal can keep Pierre-Emerick Aubameyang at the club "for many years".
The Gabon international scored his 50th Premier League goal against Norwich City on Wednesday evening as the Gunners secured a 4-0 win at the Emirates stadium.
Aubameyang has become the fastest Arsenal player to achieve that feat after robbing Norwich City goalkeeper Tim Krul of the ball and then tapping it in.
However, Arteta hopes to see the striker continue his career at Arsenal beyond next season.
When Arteta was asked how many more goals Aubameyang can score for Arsenal, the Spaniard told a post-match media conference: "Hopefully at least another 100. I don't know, I'm not a magician.
"What he's achieved today to be the fastest in the history of this football club shows everything about his mentality and the way he works every day on his finishing, on trying to help the team and his desire to be better and better every day. Hopefully, we can keep him here for a longer period.
"He's willing to stay with us, I think he's really happy where he is, and he can see what we are trying to do.
"Hopefully he can evolve some parts of his game and he can improve. We are pushing him every day towards that."
On the progression of talks over a new contract, Arteta said: "I don't know, I leave that to the football club.
"Auba knows really well what my thoughts are towards him, the project that I want to create and how much he's part of that, and after that, it's not in my hands.
"I'm positive and I can remain positive that we can keep him here for many years, but things have to progress."
