Liverpool Football Club have confirmed the sale of Gabriel Paletta to Argentine side Boca Juniors.
The young centre-back had been at Anfield since the summer of 2006.
Liverpool snapped him up from Banfield following impressive displays in the 2005 FIFA World Youth Championships.
Argentina won the tournament, with Paletta playing in all seven games alongside the likes of Lionel Messi.
The 21-year-old made his Reds debut on October 25, 2006 in a 4-3 League Cup victory over Reading at Anfield. He capped an impressive display with a second-half goal.
Liverpool have been boosted by the return to light training of left-back Fabio Aurelio.
The Brazilian, who has made 25 appearances since arriving at Anfield from Valencia a year ago, has been missing for five months after rupturing his Achilles tendon against PSV in April.
Aurelio could make his return to the first team within weeks.
