The former England U21 international has been in top form for the Eagles this season, and has been linked with a string of Premiership clubs.
However, he insists his top priority is to reach the Premiership with Palace.
"Obviously it's brilliant when you hear that Premiership clubs are interested in you - but I just want to concentrate on Palace," he told the Croydon Advertiser.
"If I keep working hard things will take care of themselves - but first things first, I want to help Palace get promoted. "I'm confident I've got what it takes to be a Premiership player - but this is where I want to be at the moment."
