Pierre-Emerick Aubameyang has said he could leave Borussia Dortmund this summer but suggested he may not join his dream club Real Madrid.
Aubameyang, who has also been linked with Manchester City and Paris Saint-Germain, told new German daily Fussball Bild it is "100 percent" certain he will remain at Dortmund until the summer but could not promise he would still be at the Westfalenstadion next season.
"Nobody can foresee the future," the 27-year-old said. "I love it at Dortmund, but I can't say that I'll stay for two more years, or five or 10. It's possible that a club could reach an agreement with Dortmund in June and I'll go."
Aubemeyang, who has scored 16 goals in 15 Bundesliga games this season, added: "I want to be honest: When you are ambitious and also want to see something else ... it's difficult to talk about. Some players have ambitions, and therefore they leave and want to experience something new, you know."
However, the Gabon international has said it is not certain he will move to Madrid, despite having said on numerous occasions that he had promised his grandfather he would play for Los Blancos one day.
When it was put to Aubameyang that Madrid were his "dream club" if he were to leave Dortmund, he replied: "Yes, yes. That's true but, you know, there is not only Real Madrid in this world."
Sport Bild reported in recent days that Madrid boss Zinedine Zidane is looking for a different type of player.
"I don't know if that's true but, also, I am not interested in it," he said. "If Real want me, they will call me one day and, if not, no problem. I live my life and am optimistic about the future."
The Daily Telegraph reported this week that Manchester City -- who had been strongly linked with Aubameyang last summer -- retain a "strong interest" in the player, while PSG have also been linked.
Fussball Bild suggested he could be tempted by a reunion with his former coach Jurgen Klopp at Liverpool, but he replied: "I don't think that'll happen."
Aubameyang also said he would not become the latest Dortmund player to make the move to domestic rivals Bayern Munich, with Mario Gotze, Robert Lewandowski and Mats Hummels all having made that switch in recent years.
"I would never join Bayern," he said. "That's for sure. That would be too hard on the Dortmund fans. Whatever they'd offer me, I'd say no."
Aubameyang is currently playing at the African Nations Cup in Gabon, where he has already scored two goals for the host nation. However, they have drawn both their games so far and need to beat Cameroon in the final group stage match to reach the knockout stage.
Should Gabon fail to qualify for the next round, Aubameyang could return to Dortmund next week.
