The 34-year-old Blues midfielder's current contract at St Andrews runs out this summer but he has said that he will not rush into making a decision on his future.
He said: "I'm not sure what I'm going to do. I'm going to weigh up the options in the summer.
"At the moment the manager has said to me the club are going to be offering me another year. Whether that happens or not, I don't know. They were meant to give me another year last summer.
"I'll be on a free now and I'll see what options I get and go from there. I've not had a bad season so I might have a couple (of years left)."
"I like playing football. I don't come to work to sit on the bench. The games I do miss, I don't like. I had a spell here this season when I wasn't playing and I wasn't happy.
"But I think for one reason or another since Christmas time, the manager has put me back in and been playing me.
"I'll have to weigh things up. No-one is guaranteed to play but obviously I want to play as much as I can.
"I still feel that I give a lot to the team. That is the most important thing, that the team do well and I want to be part of that.
"There is no reason for me to go. It just depends. I can't sit here and say I'm going to stay here because I don't know what options I'm going to have. But am I happy here? Yes."
