Liverpool have signed 18-year-old right-back Emmanuel Mendy on a free transfer from Spanish third division side Murcia Deportivo.
The Spanish teenager, who can also play at left-back, is expected to compete for a place in the reserve set-up overseen by Gary Ablett.
The Reds have made several youth signings over the summer.
Mendy joins Christopher Buchtmann, Nikola Saric, Zsolt Poloskei and Vincent Lucas Weijl at Anfield.
Manager Rafael Benitez has added Philipp Degen, Andrea Dossena and Diego Cavalieri to his senior squad.
