Marseille v Arsenal (Kick-off 7.45pm). On RTE, you'll have four dinosaurs quibbling with each other under very unforgiving lights, on ITV< you'll be greeted with the sight of Adrian Chiles... Tough call. Anyway, they'll all be trying their best to present all the action from the matchday three Group F encounter at the Stade Velodrome, as the sides meet for the first time in their histories. The Gunners have so far earned a draw away to Borussia Dortmund and beaten Olympiakos at home, while the French outfit claimed victories in both of their opening matches against the same opposition, meaning a win in this encounter for either team would put them in a strong position to qualify for the last-16 stage.
