Arsenal's job is clear - they need to get a point out of this game. A loss isn't the worst thing in the world, I guess, but every point gets Arsenal away from the dreaded third place spot and its resultant trips to far-flung European locations on Thursday nights.
Unfortunately, Arsenal will need to get that point without a good number of their starters, and with Mathieu Debuchy. I really, really want Debuchy to be better than he is, and I root for him to be better, but so far he's...not. I hope that the prospect of playing the best team in Europe right now lights a fire in him, and that the undercurrent of "I hope this isn't a slaughter" running through the Arsenal fan base right now lights a fire in the team.
