Pierre-Emerick Aubameyang says a move to Borussia Dortmund would interest him but he has not ruled out a switch to Paris Saint-Germain.
Aubameyang, 23, scored 19 league goals this year and is being chased by a host of top European clubs with Dortmund and Bayer Leverkusen being the latest teams to have been credited with an interest in the Gabon international.
Although the striker has not made a decision on his future yet, he says a move to Germany's top flight is an option he would consider.
"The club [Bayer Leverkusen] have expressed an interest to Saint-Etienne and my father," he told RMC. "During each match I was being watched. They have an interesting project, but I have to consider all offers. There is also Dortmund.
"Today, there are major championships such as Germany and England. I see myself in one of these countries but my dream is still to play in Spain. I still have much work to go to a big club like Real Madrid. But I'm leaning more towards a move to Germany because it is a league that is improving."
The forward also did not rule out a possible switch to Ligue 1 champion PSG, though no official offer from les Parisiens has been made.
"[The possibility of a move to PSG] is not to be neglected," he added. "But we need a proposal. If it is done, I will investigate it. The project could be interesting since the club plays in the Champions League."
Aubameyang helped Saint-Etienne win the Coupe de la Ligue, the club's first major trophy in 32 years, in April, but concedes it is unlikely that he will stay at the side beyond the summer.
"There is a good chance that I will leave the club," he continued. "The proposals are there but you have to leave it with the board now.
"I do not know at all where I'm going, but I think it was my last season at Stade Geoffroy-Guichard."
