The veteran midfielder, who has spent 11 years at Stamford Bridge, is out of contract in the summer but gave no indication as to what might lie ahead in 2013.
"I will keep trying to give my best as I've always done when here and will continue to do so," he said. "I just hope to keep playing in a winning team.
"We haven't been talking about a new contract. At the moment nothing has been said and my contract is up in the summer.
"I know there's a lot of speculation and talk, but for me the enjoyable bit is the 90 minutes.
"We put in a huge effort, especially after the sloppy start. The lads dug in, we held our own, rode our luck. But I think we made our own luck and I think we deserved to win it for that.
"To be able to contribute and get the goals is great, but the team deserve the most credit for their hard work."
