The 26-year-old French interntional was the subject of interest from Roma and Tottenham in the summer.
A possible move to Spurs was close and Harry Redknapp confirmed talks were ongoing - but the deal fell through.
Now back at the Santiago Bernabeu he is yet to feature this term, but he is hopeful of becoming involved.
"I am a Madrid player and I intend to stay here until the finish of my contract," said the former Arsenal and Chelsea midfielder.
"I have a contract with Madrid until 2013 and would like to fulfil that commitment.
"My goal now is to earn a starting place, and I am working hard for that."
