Christopher Jullien

Christopher Jullien (born 22 March 1993) is a French-Martinican professional footballer who plays as a centre-back for club Montpellier. He is a Martinican descent, former France youth international, having represented his country at under-20 level.

Early career and Auxerre
Born in France, origin from French island, Martinique. After failing to earn selection into the prestigious Clairefontaine academy, Jullien joined another local Parisian club, Torcy, the same club that produced France national team's Paul Pogba. He then left in 2006 for Auxerre.

After a year spent playing with the club's reserve team, former coach Jean-Guy Wallemme started playing him during the 2012–13 campaign in the second division. He made his club debut on 24 August 2012, when Auxerre won 2–1 against Laval. Jullien scored his first professional goal a week later, in a League Cup match against Dijon.

SC Freiburg
Jullien signed his first professional contract with SC Freiburg on a free transfer, after Auxerre failed to do so in the summer of 2013. During his first season in Freiburg, although he only appeared for the second team, he played in the fourth tier, the Regionalliga.

Loan to Dijon
In late June 2015, Jullien was loaned to Dijon in Ligue 2.

Toulouse
On 1 July 2016, Jullien signed a four-year contract for Ligue 1 side Toulouse.

Celtic
On 28 June 2019, Jullien signed a four-year contract for Celtic. He signed for a fee rumored to be in the region of £7 million, which would make him Celtic's second most expensive signing (after fellow Frenchman Odsonne Édouard, who signed for £9 million the previous summer).

In the following game against Romanians CFR Cluj, Jullien was left on the bench as Celtic crashed out losing 4–3 on the night and 5–4 on aggregate in a Champions League Qualifying 3rd round 2nd leg tie. He scored his first goal for Celtic in a UEFA Europa League qualifying tie against AIK on 29 August 2019. He suffered a head injury in a game in September 2019.

Jullien won his first domestic trophy, scoring the only goal in a 1–0 victory over Rangers in the 2019 Scottish League Cup Final on 8 December at Hampden Park.

Montpellier
