The 30-year-old is entering the final year of his Arsenal contract and decisions have to be made.
In a new interview, Aubameyang says he has yet to receive an official contract offer from Arsenal.
“Recently I have not received an offer to extend,” Aubameyang told Téléfoot. “But, of course, we have had exchanges with the club for a fair few months now.
“They know very well why so far nothing has happened. They have the keys. It is up to them to do their work and, after that, we will see how things go.
“It’s a turning point in my career and I will be very frank with everyone, it will be of course a very difficult decision to make because I have still not decided.
“This is possibly the most important decision of my career. To be clear, nothing has been decided.”
Aubameyang has been a big hit at the Emirates Stadium since joining from Borussia Dortmund for €65m.
The Gabonese striker has scored 61 goals in 97 appearances for the Gunners.
