Sunderland reportedly wanted to sign Ryan Christie in the summer, too, but a stay in the Scottish Premiership with Celtic looks likely.

Jack Ross’s time in Scottish football with St Mirren could open up some doors for Sunderland.
After all, there are plenty of bargain signings to be had north of the border and Ross’s knowledge of the Scottish game has seen the Black Cats pick up both John McLaughlin and Dylan McGeouch on free transfers.
And it seems that Ryan Christie was the next name on their wish list.
The BBC claimed in August that Ross wanted to bring the talented Celtic midfielder to the Stadium of Light and, after Christie scored three times in his last four games for the Hoops, it seems that his impressive form had not gone unnoticed.
The Chronicle is now reporting that Sunderland were continuing to monitor Christie’s situation, with his contract due to expire at the end of the season.

Although it seems that their hopes are over now. After spending the last year and a half on loan at Aberdeen, the 23-year-old has finally forced his way into the Celtic starting XI over the last few weeks and has now been rewarded with a new three-year contract, putting an end to any speculation over his future.
It seems that Sunderland have seen a very impressive talent slip through their grasp.
