Borussia Dortmund have reportedly identified three English prospects as future signings.
The Bundesliga giants brought in Jadon Sancho from Manchester City in 2017, and the acquisition of the 18-year-old has so far proven to be a success.
According to The Mirror, that has resulted in Dortmund monitoring the progress in the careers of Phil Foden, Callum Hudson-Odoi and Bobby Duncan.
Both Foden and Hudson-Odoi are highly regarded at Manchester City and Chelsea respectively, but neither of the creative pair are featuring regularly for the first team.
Forward Duncan is still someway short of making his senior debut at Liverpool, but the 17-year-old was recently provided with the chance to train with Jurgen Klopp's squad.
Foden and Hudson-Odoi both have a contract until 2020, while Duncan's deal is due to expire in 2021.
