The 23-year-old has scored 15 goals for his French club this season, leading to suggestions that a host of European sides were monitoring his progress.
"I am happy with my form again. Scoring is important for a striker and I am on a good run at the moment," Aubameyang told reporters at a press conference.
"I would love to finish the season strongly for my team and put us in a strong position to fight for a Champions League place.
"If we qualify for that competition it would be difficult for me to leave the club. But my future will be decided at the end of the season."
The Gabon striker is understood to favour a move to the Premier League.
