CHRISTOPER JULLIEN wearing a Celtic strip has become a rare sight over the past 18-months.

The French defender suffered a horror injury in December 2020 after clattering his knee of the post at Celtic Park.

Since then, he has been limited to just 16-minutes of first team action under Ange Postecoglou. 

It's believed that the 29-year-old could be headed for the exit door this summer.

However, in the mean time, Jullien has been keeping his fitness levels up while working out in a Celtic training jersey.

He uploaded a training video on Instagram this morning as he worked out wearing his Hoops kit.

As things stand, he will return for pre-season training in just under two-weeks time with the rest of his Celtic teammates.

It remains to be seen how many more times fans will get a glimpse of the towering defender in green and white colours.
