Cardiff are set to lose their current left back Joe Bennett to Fulham. It is no secret that the Bluebirds have been interested in Cunningham for some time going back to last season.
No offers appear to have been made and Preston have confirmed that their captain is not for sale and the club would be foolish to let one of their top players go to a Championship rival.
North End have had a host of enquiries for players over the past few months no thanks to the improved standing of the club over the past two seasons but Preston can ill afford to lose thier best players to rival clubs.
