Le Havre vs PSG tonight — how do small Ligue 1 sides even try to set up against them?

Le Havre host PSG and the template most underdogs use is familiar: compact low block, keep the half-spaces closed, hope the keeper has the night of his life, and pray for a set piece. The problem is PSG now press so aggressively that sitting deep just invites them to camp in your half for 90 minutes. If you were Le Havre's manager, would you park the bus, or press high early and try to rattle them before the legs go?
