Liverpool boss Rafael Benitez has signed defender Mauricio Pellegrino from Valencia on a free transfer.
The 33-year-old has agreed a six-month deal with the option of a further year, after an injury-hit season in La Liga.
Pellegrino joined Valencia in 1999 from Barcelona and helped them to Champions League finals in 2000 and 2001.
The Argentine also played in the Spanish title-winning sides of 2002 and 2004, and last year's Uefa Cup final win over Marseille under Benitez.
His agent Filippo Cavadini said: "He has passed his medical and is very happy he is going to Liverpool - a great club.
"He has already spoken to Rafael Benitez and is looking forward to playing with Liverpool."
"Mauricio will now be going to Valencia for two or three days to organise his personal situation before returning to Liverpool."
The 33-year-old told the Liverpool club website he was thrilled to have the chance to join the club.
"I feel very satisfied," said Pellegrino.
"At my age it's a great satisfaction that this opportunity comes along. I have always wanted to play in English football."
