It’s a big game for…

Aaron Ramsey: The Welshman could start his first match since the opening-day defeat to Liverpool, when he was taken off with a hamstring injury. He returned to the first-team fold on Saturday, coming off the bench and assisting Alexis Sanchez for the Gunners’ fourth goal barely a minute after coming on. Ludogorets were humbled 6-0 at the Emirates just under a fortnight ago and if selected, Ramsey will fancy his chances of doing some damage.

Best stat…

Olivier Giroud scored two goals with his two touches after coming on as a substitute on Saturday against Sunderland – the first time that has happened.

Remember when…

Arsenal topped a group consisting of Marseille, Olympiakos and Borussia Dortmund in 2011-2012? It was the last time that the Gunners had topped a Champions League group.

Player to watch…

Olivier Giroud: The combination of a rest period following the Euros and a toe injury has limited his opportunities this term. However, two goals with as many touches on Saturday illustrated his ability (albeit against poor opposition). Ludogorets could provide similarly easy pickings.
