Liverpool boss Jurgen Klopp is watching PSG defender Presnel Kimpembe.
The young stopper has attracted enquiries from Chelsea this season, while St Etienne and AS Monaco have also sounded out PSG about a loan deal.
El Mundo Deportivo says Klopp made a serious attempt for Kimpembe over the summer.
The Reds manager made attempts for several young central defenders - including Kimpembe. However, PSG president Nasser Al-Khelaifi refused to do business.
Kimpembe has a contract with PSG to 2018.
