During the summer transfer window, Celtic were reportedly willing to offload Ryan Christie.
Sunderland were keen to bring him on loan with an eye on a permanent deal in January. Jack Ross hoped to tie up a loan deal for the 23-year-old who is out of contract next summer.
“Ryan is a player that I like, he has good qualities but again it is a balance between what we need in the squad,” said Ross in August as quoted by The Scottish Sun.
