CHRISTOPHER JULLIEN faces being frozen out at Celtic until January after failing to attract fresh transfer interest, according to reports.

The French centre-back has not featured for Celtic this season after a switch to Schalke fell through over personal terms.

Jullien has been training with the Celtic first-team but had not been involved in competitive action with Ange Postecoglou favouring Cameron Carter-Vickers, Stephen Welsh, Moritz Jenz and Carl Starfelt returning from injury.

Now, Football Scotland report that no clubs have registered an interest in signing Jullien this summer.

However, it's claimed the defender is still hopeful of finding a new club instead of having to wait until the January window.

Jullien is into the final 12 months of his Parkhead deal having penned a four-year deal at the club under Neil Lennon in 2019.
