Qualification from Group A ought to be a formality for Arsène Wenger's men – but they'd rather finish ahead of Paris St Germain at the top of the group, and a wide margin of victory at home to relatively weak opponents would be a big step towards that goal.
The Bulgarian champions are, however, stubborn in defence. The Gunners are therefore likely to name a strong line-up: Ludogorets will hope it doesn't include the in-form Theo Walcott, who has scored five goals in his last four games.
