Coloccini declares Newcastle commitment
The Argentinian defender's future has been the subject of intense scrutiny in recent days.
But Coloccini told the club's official website: "The last few weeks there has been a lot of talk about my future. But I am staying here. And of course I will give 100 per cent like I always do.
"I have been here five years and Newcastle has given me a lot and done a lot for me. I have to be true to the club. I will give 100 per cent.
"I love football and once I am on the pitch it is different. The problems I have are outside the pitch.
"I heard in the city and around the club that the fans think I have my head elsewhere thinking about other things, or that I am not the same player as last season.
"The fans have to know and be sure that when I am the field I give 100 per cent. I am the captain of the team and I take the responsibility.
"I think everybody has problems outside of their work in life. It is difficult but now I am here and all I have in my head is to make sure we are in the Premier League next year. That is my only objective.
"I am alone here with my family. We don't have grandparents here or uncles and aunties. It does make it difficult. Not for me personally, because I come to work everyday, but for my kids and wife.
"Here though, the club and the fans are my family at the moment. The love that they give to me with my song and on the pitch for me is fantastic. It's the best present they can give me."
