Chelsea's Salomon Kalou was coy when asked about extending his contract past the end of the season after his match-winning performance in the Champions League victory at Benfica.

The Ivory Coast international scored the decisive goal in the west London side's 1-0 win in Portugal last night, prodding home in the 75th minute of the quarter-final first leg.

Kalou has been with the Stamford Bridge outfit since joining from Feyenoord in 2006, but could leave at the end of the campaign when his contract expires.

Former Chelsea manager Andre Villas-Boas claimed he had been offered a new deal before he was sacked and the 26-year-old laughed off speculation about his future after the game.

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

"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."

Kalou was proud to net Tuesday night's all-important goal and believes anything is possible in this season's competition.

"It means a lot to me to score," he said. "I am happy to be in the team, playing games and to score. I still think I can improve and if I can help teams to win games, I'd be delighted to do that.

"Anything is possible. We have the team for it, we have the players for it. I believe there is no reason why we could not win the Champions League."
