Celtic defender is celebrating an important weekend win at the home of their rivals.
Celtic centre-back Christoph Jullien put in a terrific performance as the club beat rivals Rangers.
The summer signing admitted he felt Celtic owed their fans a big result.
This was in reference to the disappointing Champions League elimination at the hands of CFR Cluj week earlier.
Celtic were terrible defensively that day, and that point supporters were wary of the team performing the same way at Ibrox.
Credit to manager Neil Lennon and his players, Celtic have completely turned it around since, winning every game.
More displays like this and Jullien will quickly become a fan favourite at Celtic.
Celtic sit three points clear now at the top of the table after this win, with four wins from four games.
They even have a chance for Europa League redemption after being drawn in the same group as Cluj.
