Cardiff confirmed the arrival of the winger on a temporary basis on Friday, and the winger admits that he is eager to impress as soon as possible.
"I've only been here a day or so, but I've had a chance to get to know the place a little bit and meet people at the training ground," the 21-year-old told the club's official website. "It's great to be here.
"I think I'll be able to contribute something to the team. I haven't seen that much of Cardiff City this season, but what I have seen has shown me that we're capable of playing good football."
Zaha is available for Cardiff's game against Norwich City on Saturday.
