Season So Far: Kurt Zouma has been steady when he's played for Saint-Étienne, but he hasn't shown the dominance Marquinhos has exhibited for Roma.
Though, it must be noted that they are two different types of centre-backs, with Marquinhos being the more proactive, hence why it's easier to notice him.
Kurt's troublesome ankle has given a mediocre defender in Moustapha Sall playing time.
The Senegalese international has noted concentration problems.
One example is when he mistimed a clearance, which led to Gaëtan Courtet scoring Stade Reims' equaliser in a 1-1 draw.
Moustapha has been bailed out on numerous occasions by the excellent Loïc Perrin, one of Ligue 1's best defenders right now, and a reliable goalkeeper in Stéphane Ruffier.
Zouma was an unused subbed at Reims and was left out of the matchday squad in the 3-0 win over Nancy.
He'll win back his starting position, presuming Sall continues to play this way.
Current Transfer Situation: Zouma has extended his contract to 2017 (per Asse.fr via Sky Sports), handing Les Verts control over his future.
This is a great idea because he'll be starting alongside a seasoned pro like Perrin, who isn't just a great CB, but also a leader of men.
In the next few years, Kurt needs to aim high, make multiple Ligue 1 Team of the Years, win the Ligue 1 Young Player of the Year award, receive the highest rating awarded by L'Équipe to a defender and be a mainstay in the French senior national team.
Once he has achieved that, he'll be ready for club of the highest quality like Manchester United.
