CELTIC outcast Christopher Jullien could be heading back to France this summer, according to reports. 

The central defender is believed to be attracting interest from several Ligue 1 clubs.

The Scottish Sun say Jullien's situation at Celtic Park is being monitored closely, with a summer move potentially on the cards.

The 29-year-old returned from a long-term knee injury recently. 

However, despite being back in first team training, he has been limited to just 16-minutes of action since.

Speaking on his future recently, he said: "I still have a year of contract and I'd like to continue playing here, but my priority is to be on the pitch.

"If the conditions do not change, it is certain that on my side the door will be open to continue my career elsewhere at a club where the coach would be happy to rely on my qualities."
