Skysports.com understands Cardiff are lining up a move for Millwall defender Danny Shittu.
Cardiff boss Dave Jones is keen to bolster his defence in the January transfer window and he has targeted a move for Nigerian ace Shittu.
Shittu is currently at Millwall after leaving Bolton in September and the powerful defender has impressed at The Den.
The 30-year-old's short-term deal at Millwall expires next month and he will be available on a free transfer.
A number of Championship sides are thought to be weighing up moves for the former QPR and Watford man, but Cardiff are hoping to steal a march on their rivals by luring Shittu to Wales.
