Now Coloccini has told Newcastle United he wants to quit the club immediately.
The Argentine skipper wants to return home to South America, for what has been described as "personal matters".
Last week his father Osvaldo told Argentine TV that his son wanted a move to San Lorenzo and despite talk from his agent that the idea was an "illusion", it has emerged that the Newcastle captain wants out at St James' Park.
It remains to be seen whether he is pulled out of the Toon squad for the trip to Norwich City tomorrow.
Coloccini only agreed a new lucractive four year deal just under 12 months ago.
San Lorenzo would have the problem of coming up with a fee and being able to match Coloccini's £60,000-per-week wages.
San Lorenzo's president, Matias Lammens said: "He represents much more than football – he played here six months and was champion, his father works at the club and is a fan. The deadline is next week but we cannot do anything crazy with the budget."

The Telegraph reports - "Fabricio Coloccini wants to leave the club to join former team San Lorenzo, according to his father."
The Argentine is "trying his best to find an elegant way to leave" according to the youth team director at his former club, but says his contract could complicate matters.
Coloccini's father, Osvaldo, who represented San Lorenzo as a player and is now the youth team director, and says that the defender is keen to return to the team he represented over 10 years ago, on loan from AC Milan.
"Fabricio wants to play for San Lorenzo and he is trying his best to find an elegant way to leave Newcastle," Coloccini's father told Indirecto on TyC Sports.
"We don't know what Newcastle will come up with, but Fabricio is trying to rescind his contract because he wants to be back at San Lorenzo.
"His contract is very good and that could complicate things in an attempt for him to leave Newcastle."
Coloccini joined the Magpies in 2008 from Spanish side Deportivo La Coruna for a fee close to £10 million.
But Alan Pardew had a go at the defender after the fixtures at Old Trafford and Arsenal, suggesting he was "well below his normal form".
