However, Robbie and his agent Gordon Armstrong have turned down that offer and the player has decided to move elsewhere with suggestions that two other clubs have put two year deals on the table.
"The offer is a 12-month deal with a further one year option, but Robbie wanted two years and we just couldnt't go down that road. We included the extended deal should Robbie play 20 games next season and I feel a fit Robbie would have easily achieved that.
"So naturally I am disappointed, but I would like to thank Robbie for all his magnificent service for the club. I know he is a firm fans' favourite and he is rightly considered a legend here, who will never be forgotten.
"But I have told Robbie and his agent that we have left the door open and if he has a change of mind I would be more than happy to talk."
