Bayern München, Barcelona and Liverpool are said to be interested in RB Salzburg and Germany striker Karim Adeyemi.
According to Bild, Bayern München, FC Barcelona and Liverpool are keeping tabs on the 19-year-old.
Munich-born Adeyemi played for Bayern München as a youth player, but was eventually released by the Bavarians.
"I want to show them what I can do, who I am and that it was a mistake to sort me out. That spurs me on," Adeyemi said in June.
Adeyemi scored in his debut for Germany's senior national team after coming on from the bench in Sunday's 6-0 victory over Armenia.
The young forward has netted six times in his first six league games for Salzburg this season.
