Salomon Kalou is calm about his future at Chelsea.

Kalou proved Chelsea's matchwinner in victory at Champions League opponents Benfica.

"I know my contract ends at the end of the season," said Kalou.

"For me the most important thing is not to fight for a new deal, it is just to enjoy myself with the team and play the best I can and help the team win the games we have left to play.

"As long as I do that, I am fine and I am happy with myself."
