Newcastle United captain Fabricio Coloccini wants to leave the club for San Lorenzo but wishes to depart in 'elegant' circumstances, according to the player's father.

The Argentine centre-back is seeking a return to his homeland in the January transfer window due to personal problems, and is currently in discussions with The Magpies over an early release from his contract which isn't due to expire until 2017.

But Coloccini senior has again confirmed his son is eager to leave Newcastle in January, but the move hinges on whether San Lorenzo can finance a prospective deal.

Coloccini appears set to leave Newcastle.

"There was an inconclusive meeting today," Coloccini Snr told Rock and Closs on Monday.

"Tomorrow there will be a decision. We both desire the transfer.

"Fabricio is very anxious. He wants a decision to be made one way or another. I believe this is the moment to move.Newcastle have asked him to wait until May. The issue is if San Lorenzo will wait until that date.

"It would be beautiful if both of us were at San Lorenzo, the club we love. Fabricio is eager to return but he wants to do so in an elegant way."

Despite Newcastle being on the brink of signing Montpellier captain Mapou Yanga-Mbiwa, Coloccini's exit from St James' Park, with the club two points above the relegation zone with 15 league games remaining would come as a significant blow to their chances of avoiding the drop.

Having already signed French right-back Mathieu Debuchy, Newcastle have agreed a deal for Nancy full-back Massadio Haidara, the Ligue 1 club have confirmed.

The France Under-21 international signed his professional contract with the club in 2011 and has since been a near ever-present at left-back.

With Ryan Taylor out for the rest of the season, Haidara will provide competition at full-back alongside Davide Santon, and could be utilised in the Europa League knock-out phase against Metalist Kharkiv.

"After 46 games and two-and-a-half years in the Nancy shirt, Massadio Haidara is leaving his former club for Newcastle United, currently sixteenth in the Premier League," a club statement read.

"The two clubs have reached an agreement and will finalise the transfer on Tuesday."

The Toon are continuing to suffer problems in their attempts to replace Demba Ba, who joined Chelsea earlier in the window, with Yoan Gouffran the latest forward to be linked with a move to the north east.
