After the European Champions season, the addition will be the Argentine youth national team and "Atletico Banfield" center-back Gabriel Paletta.
The defender, who will turn twenty on Wednesday, has agreed to a four-year contract with Rafael Benitez-led team, which he will sign after passing a medical examination.
Many South American and European giants were interested in the young talent, but "Liverpool" won the race for the defender.
This season, G. Paletta has played 33 matches for "Banfield", scoring five goals, and last year he helped Argentina win the Under-20 World Championship.
"Liverpool" strengthened their squad during the winter transfer window with young Danish talent center-back Daniel Agger and Dutch right-back, who can also play in the center of defense, Jan Kromkamp.
