CHRISTOPHER Jullien is an intimidating physical presence, but he probably hasn’t been used to the challenge posed by Livingston striker Lyndon Dykes on Sunday.

Jullien has really come good and played exceptionally well against Cluj, but he probably epitomised the drop-off in performance of Celtic come the weekend.

He wouldn’t have been used to that sort of environment or that sort of contest in France, where someone is bashing him about. He looked startled by it.

If a player is physical against you, you have to match it, but the last thing you do is allow that to visibly affect your performance or sidetrack you from what you are meant to be doing.

It became a personal battle between the two, and Jullien lost his focus on the game as a result. He let his opponent know he was getting to him.

Fair play to Dykes, but Jullien shouldn’t have allowed the Livi man to distract him from just playing his game.
