Reports have suggested that newly promoted Birmingham will make a move for the 31-year-old who still has two years of his contract remaining.
It was also reported that Celtic were interested in taking the midfielder north of the border.
Speaking to the official web site he said "I am happy here. I appreciate what the club has done for me,"
"Whether my name has been mentioned to other clubs, I am very loyal. Unless I am told different, I will be here as long as my contract is running."
He went on to say " . . . I am delighted to be the captain - it is a big honour - and if I am appreciated for what I do for the club, then there will be no changes."
