Naby Keita could become a Liverpool player earlier than expected if the Anfield club decide to pay up an additional £13 million.
The Reds have already agreed a deal worth £48m for the midfielder that will see him move to the Premier League next season.
However, Jurgen Klopp has been given encouragement that RB Leipzig could be willing to let their man go earlier after his form has suffered since the summer.
German outlet Bild reported that the Bundesliga outfit were open to the possibility of letting their star-man go in the winter window, a claim which the club are refuted in public.
