The fringe starter with perhaps the most to gain out of Saturday's visit of Reims is Marquinhos, Paris Saint-Germain's Brazilian defensive wunderkind.
He's a centre-back by trade but has the confidence, calmness, mobility and ball-playing skills to deputise as a right-back. He played there for Roma several times toward the end of the 2013-14 season and could fill in here.
Laurent Blanc asked Edinson Cavani to help Christophe Jallet extensively on Wednesday, fearing what Eden Hazard would do to him if he didn't have an extra body in cover.
With Cavani moving central, will Lucas Moura provide the same protection? If he can't be trusted to, then Marquinhos could get the nod ahead of Jallet thanks to his superior defensive skill set.
