He's had a week off. No need for a rest. All our players eventually succumb to a long-term injury anyway so he might as well be used while he's in good form.
WUMger will reward Giroud for his stupidity by handing him an instant start on his return rather than stick with the flexibility, movement, speed, directness and unpredictability that a similar forward line to the one versus Hull would offer. The midfield should stay the same too, as it had more balance and fluency than we've seen in a while. Ozil and Flamini straight back into the team too, then.
2-0.
