The Dutch midfielder, who made only his sixth start of the season in Saturday's FA Cup triumph over Colchester, is out of contract in the summer.
The 31-year-old told the South Wales Evening Post: "I'll just wait and see what happens.
"I haven't been playing a lot of football lately and I've had my talks with the manager as well.
"All I can say is that when I play I'll do the best I can - that's the only thing you can do as a player.
"It's January and the transfer window is open so we'll have to see what happens."
