Liverpool are chasing Bayer Leverkusen pair Emre Can and Heung-Min Son.
The Daily Star Sunday says Kop boss Brendan Rodgers has personally checked on both players.
Can, 20, has been compared in style to former Germany captain and ex-Chelsea midfielder Michael Ballack.
Son, 21, meanwhile, can operate up front or as a second striker. He is a target for all Europe's top clubs.
Both players are valued at £12 million.
