Every Celtic player's contract and transfer status including Joe Hart and Kyogo

Celtic have been guilty of letting too many players run into the final year of their contracts and missing out on transfer value for key stars. Ryan Christie, Odsonne Edouard and Kristoffer Ajer all left for cut-price fees last season after refusing to pen fresh deals. The Hoops entered a new era with chief executive Michael Nicholson being appointed as Peter Lawwell's successor and Ange Postecoglou taking over the reins as manager.
