Devenny has been played in an advanced role by manager Oliver Glasner this season.
He told Palace's website: "It’s a hard one. I’m learning every day on the training pitch. Regardless of what position I’m in I’ve still got lots to learn.
“Across my career I’ve probably played as a six more, as a central midfielder. But every time I’ve played as more of a number ten, I’ve loved it.
"My aim is to get on the pitch, regardless of position. But now I feel like I know what to do in every role.
“I want to make an impact, and score goals, and assist, and tackle. I don’t want to say I’ve got a preference on position, because I don’t want to limit myself.
“I want to be ready whenever needed, I want to be versatile. Obviously, everyone has to establish their position, but I feel I can do that.
“At the end of the day I love playing football and if I can play freely, it will bring the best out of me.”
