Sunderland are still looking to add to their squad this summer as they aim for promotion from League One.
The Celtic midfielder has found life at Parkhead difficult and it appears Jack Ross is prepared to offer him a way out of Glasgow.
It is understood that Sunderland are keen on tying up the 23-year-old on an initial loan deal, with a view to signing him permanently once the transfer window in England opens back up again in January.
Christie has spent the last 18 months or so on loan at Aberdeen, and with his contract set to expire next summer, Celtic are prepared to listen to offers for the Scotland international as it is believed that they will not hand him a new deal.
Ross is keen to add a few more additions to his side and Christie could be an excellent signing.
The midfielder will be keen to force his way into regular first-team football and he would have the chance to do that with Sunderland.
Should the Black Cats and the Bhoys agree to a deal with a loan-to-buy arrangement, then it would make sense for the 23-year-old to be playing his football at the Stadium of Light this season.
