Cardiff City have made Aston Villa midfielder Peter Whittingham their first outfield signing of the January transfer window.
Whittingham has fallen out of favour at Aston Villa
The 22-year-old, who would have been out of contract at the end of the season, signed for a reported fee of £350,000 after passing a medical.
"I've played over 50 games in the Premiership so hopefully I can bring something to the team," he said.
"The move only really came about a week or so ago but I was happy to do it."
The 22-year-old former England Under-21 international has played only four times for Villa this season, and was a transfer target for Cardiff last year.
"Everyone knows what a massive fan base the club has got and the manager sold the club to me," he added.
"Hopefully I can now settle down in a midfield role."
Whittingham broke into the Villa first team in the 2003-04 season after coming through the club's youth system.
But he has struggled to hold down a first-team place and went on loan to Championship side Burnley in February 2005 before joining Derby in a three-month loan deal the following September.
