According to German media, Liverpool coach Klopp hopes to sign Dortmund's new star Renner.
Although only 17 years old, Renner has become a key member of Dortmund's first team.
Now Reina may follow in the footsteps of his predecessor Pulisic, and he may also land in the Premier League from Dortmund.
The report said that Klopp was surprised by Renner's talent, and he hoped that the American star would return to England.
Renner was born in England. His father Claudio Renner was a famous player in the Premier League.
Claudio Reina has played for Sunderland and Manchester City, and now his son may also play in the Premier League.
