Mikel Arteta said that was "pretty convinced" that Pierre-Emerick Aubameyang would stay with Arsenal.
Aubameyang has been the frequent target of transfer rumors.
"The way I look at him when I speak with him, he sounds pretty convinced. But obviously if he can see that success and the direction we are taking is the right one, I think he will be more positive about it yes," said Arteta.
The 31-year-old's contract is expiring next season.
Aubameyang is reportedly looking for a three-year contract extension.
