He joined on loan from Bolton on the final day of the loan window and hopes he can play a part in a Cardiff City promotion.
"It's going to be a good test for myself here. I have come here to play games. I want to get my sharpness and fitness back and at the same time help Cardiff to promotion," Samuel told the club's official website.
"I've been out for five-and-a-half months with an injury. It was hard to get my way back into the Bolton side because they have been doing so well.
"Rather than sit around, I wanted to come here and push on. The games will be coming thick and fast now and the Championship is a good league.
"I've played in the Premiership for most of my career which has been good for me, but now it's going to be a nice test here because they are playing for something here. They want to push on for promotion. What Cardiff have got here is a Premiership set-up really."
