The French defender missed a chunk of the season due to a back injury, but returned to the Celtic line-up away at Sparta Prague last week.

 

The Frenchman looked rusty and was poor as Celtic produced another bad defensive performance and lost 4-1, which ended their hopes of qualifying for the next round of the Europa League.

 

 

Jullien was again in the team against Ross County and was responsible for giving away a penalty as the Bhoys crashed out of the Scottish League Cup following a 2-0 defeat at home.

 

His absence was often touted as the reason Celtic were defending poorly, but McManus is of the view that the Frenchman has been poor since his return and has looked out of sorts.

 

 

The former Hibernian attacker said on PLZ Soccer: “Jullien has come into the team and he has been hopeless in the last two games.

 

“He doesn’t snuff out danger, he doesn’t see people behind him.

 

 

“Again for the penalty kick, the ball was played across the goal and he had no idea that the striker was behind him and he fouled him.

 

“It was the same against Sparta Prague the other night.”

 

Celtic have won just twice in their last ten games in all competitions with their defence playing a key role in their poor form.
