In the end, the where is less important than the who. Are you watching with a mate who yells “FORWARD!” every two seconds? That’s fine. Are you alone in your underwear, screaming at a laptop? Also fine. The Arsenal Champions League experience is a spectrum, from the comfy couch to the sticky-floored pub to the freezing cold nosebleed seats.
So pick your poison. Get your snacks ready. Roll your lucky socks up. And remember: if Arsenal concede early, just take a deep breath. It’s only football. Or as we call it, Tuesday.
