Rennes plays an expansive high-press system that dominates possession but leaves their defense highly vulnerable. Auxerre has recently shifted to a resilient low block, capable of sitting deep to absorb pressure and striking on the counter-attack. The match will likely see Rennes pinning Auxerre back early, with the game opening up as Rennes commits more bodies forward.
Rennes' high defensive line will face a stiff test against Auxerre's transition targets in the spaces left behind. Auxerre's makeshift midfield trio must maintain strict positional discipline against Rennes' experienced core. Although Auxerre has missing players, their expected replacements are fully capable of maintaining their defensive structure. The game flow points to Rennes controlling the ball while Auxerre exploits transition spaces. That's why I'm siding with Auxerre to keep this game tight and potentially punish Rennes' leaky defense.
