A number of clubs are expected to be in the market for the 24-year-old in the summer, but the frontman has insisted that he is only focused on representing Belgium at the World Cup.
At a press conference, the 24-year-old told reporters: "Dortmund was a great experience for me. They welcomed me very warmly. I was in a good environment and you could see that on the pitch.
"It was a while since I had played so much. I can't remember being allowed to play two games in a row at Chelsea. It was good to gain confidence.
"I don't have a preference; they're two beautiful clubs. My focus is on the World Cup right now and I don't want to think about what happens afterwards."
Batshuayi still has three years remaining on his contract at Stamford Bridge.
