The Argentina under 21's defender was signed last week and Rafa Benitez was quick to praise the defensive qualities of his latest aquisition.
"Gabriel is totally different to [fellow new signing] Fabio Aurelio," said the Liverpool boss.
"He is more aggressive, very competitive and is good in the air. I always say he is similar to Carra, but he is a player who will need some time because he needs to improve.
"He also needs to learn the language, but he can be very good for us."
