Cork who was on loan at the Ricoh Arena last season is currently on loan at Burnley but can leave his parent club Chelsea thanks to a clause in his contract which allows him to leave if a permanent deal is offered and that offer agreed by Chelsea, who are believed to want around the £1.5m mark.
Cork has been on loan to Bournemouth, Scunthorpe, Southampton, Watford, City and Burnley whilst at Chelsea.
