Is he more hyped than Bojan Krkic was? He had no clear physical advantage against his opponents and his goal-scoring record at youth level was also absurd if I recall correctly.
I'd say so, yes. Every time he broke some record or scored a hat-trick it has been widely reported in German media. Bild even wrote about his transfer in 2016 when he was twelve. A lot of Dortmund fans I know have had today's date in the back of their minds for months. The only one I can think of in recent years who was more hyped in his youth was Neymar.
