The Newcastle United captain has a year left on his current deal but has not played since 13 February.
Newcastle United captain Fabricio Coloccini has told Argentine radio station Closs Continental that he wants to return home this summer rather than staying with the Magpies in the Championship, as quoted by the Chronicle.
Coloccini began the season as captain and a key figure in the Newcastle defence, but after getting injured in mid-February he did not play again before the end of the season as questions arose about his commitment to the club's cause.
The 34-year-old only signed a new two-year deal at St. James' Park last summer, but with Jamaal Lascelles and Chancel Mbemba emerging as the preferred central defensive partnership, he looks to have been reduced to a bit-part role at the club.
Coloccini has over 250 Newcastle appearances to his name and stuck with the club upon their last relegation in 2009, but appears to harbour desire to leave England and return to South America this time around.
Radio station Closs Continental quotes the defender as having said, as reported by the Chronicle: "I want to return to Argentine football. I have one more year of contract but due to the club’s decline Newcastle now have another project.
"If there is a chance to return, the priority will be San Lorenzo."
It is unlikely that many Newcastle fans would mourn the departure of their former hero too much, with Coloccini's performances having become increasingly erratic this season before his injury.
Having been with the club since 2008, he is also likely to be a relatively high earner, and a move back to Argentina for the veteran would likely suit both parties.
