The Catalan giants could not have hoped for a better start to life under Hansi Flick, recording five successive victories in La Liga to sit top of the standings.
Flick witnessed his side breeze past fellow Champions League participants Girona at the weekend, yet the German still has widespread injury concerns to contend with ahead of this contest.
Here, Sports Mole rounds up Barcelona's injury and suspension news ahead of the trip to Stade Louis II to face the Ligue 1 giants.
