The 20-year-old has already been linked with big clubs around Europe, such as Arsenal and Juventus.
“I have been a fan of Barcelona ever since I was a little boy,” he told Bild. “I can’t describe what it is, but the team just fascinates me. They have always had world-class players such as Rivaldo and [Luis] Figo in their team.
“Nevertheless, Barcelona are not an option for me at the moment. Wearing the Barca jersey is a dream, but I still have a lot to learn and I have to work hard before I’m ready for it.
“Bayern Munich is not an option for me. I don’t even think about something like that at the moment. I’m really happy at Werder Bremen and still have plenty of things to achieve here.”
