The duo have impressed in the Bundesliga this season as Leipzig pushed Bayern Munich for the title at one before fading, and their performances have not gone unnoticed throughout Europe.
Keita, who has been compared to Chelsea's N'Golo Kante, is said to be on the wanted list of several clubs, but reports claim that Liverpool will try and wrap up a deal quickly by offering £26million.
Leipzig will fight to keep the 22-year-old and are under no pressure to sell as they prepare for life in the Champions League next season, just like Jurgen Klopp's men.
The same can be said about striker Werner, who has taken the Bundesliga by storm when firing home 21 goals in 31 games this season.
The 21-year-old is seen as the perfect replacement for Daniel Sturridge, who appears to be heading for the exit door at Anfield, but the Reds could struggle to convince the Germans to sell their star striker.
