CELTIC defender Christopher Jullien is closing in on a move to Schalke, with the deal expected to be finalised on Wednesday.

The French centre-half has slipped down the Parkhead picking order since Ange Postecoglou took the reins of the Glasgow club last summer, and barely featured at all last term as he continued his recovery from injury.

The 29-year-old, who joined Celtic in a £7million move from Toulouse in 2019, is currently undergoing a medical with Schalke and the deal is set to go through within the next 24 hours, according to transfer insider Fabrizio Romano.

The Sky Sports transfer guru reports that the centre-half will join the German giants on loan for the 2022/23 campaign, with the Bundesliga outfit including an option to buy the centre-half for a predetermined fee in the deal.

Romano added that Jullien is currently undergoing a medical, and will put pen to paper on his contract once it has been completed.
