The Welshman joined the London outfit last summer, but fitness and injury problems have limited him to just six league appearances for the club.
"As a footballer you always want to play. It's been a stop-start kind of season for me," he told reporters at a press conference.
"I joined late and the team was doing really well and I couldn't really get in the team which was understandable, and when I did play a few games I ended up getting injured which was disappointing.
"It's been a bit of an up and down season but the lads have been fantastic. I'd like to stay in the team if I can."
Palace currently sit fifth in the Championship table.
