The 21-year-old spent a season on loan at the Liberty Stadium after the Swans first won promotion to the Premier League in 2011, but joined the Bluebirds in an £8m deal from Tottenham Hotspur this summer.
"Going into the Swansea game, it will obviously be a very hostile atmosphere," the England international told Sky Sports News. "It's one I look forward to playing in and being involved in.
"I have heard a lot about it over the years, so I will be excited for that game. It will be a tough test.
"I enjoyed my time there and I have got a lot of respect for the club but when we do play them, I will be looking to get the better of them."
Cardiff are 16th in the table with nine points from nine games.
