The young winger, who is just 22 years old, is being considered as a potential target for Liverpool.
Per BILD, the Reds have been watching Adeyemi in the Bundesliga this term.
They are very keen on bringing him in if he continues his present development.
The German scored three times in a 7-1 win over Celtic in the Champions League in midweek.
Adeyemi would not come cheap, as the Reds would have to pay around £42.6M to land the talent.
