The Frenchman's contract is up at Stamford Bridge at the end of the season and he knows the current campaign could be the most crucial in his career.
"Since I arrived here I've started in every game and that's what I needed," he said. "I'm feeling more and more comfortable physically and my confidence has improved too.
"I want to have a full season and see how it goes. Right now I'm a player of Chelsea but I'm playing for Rayo so now I'm just focused on Rayo, we'll see what happens at the end of the season."
