The 31-year old centre-back was being heavily linked with a return to Argentine club San Lorenzo in the summer and again that speculation has surfaced but he insists he is in no hurry to leave St James' Park.
"At the beginning of the year, due to some personal problems, I had the chance to return to Argentina," he told Marca.
"It was spoken about playing in San Lorenzo because I support that team. I am currently very happy at Newcastle - I have three more years on my contract.
"While I keep on being useful for my team on the pitch, I will keep on playing."
