Arsenal can all but guarantee their place into the last 16 of the Champions League with a victory over Ludogorets on Tuesday night.
The Gunners will move on to 10 points with a victory in Sofia against their Group A opponents.
Elsewhere in Group C, Celtic know only a victory will suffice in Germany when they visit Borussia Monchengladbach. The Scottish giants currently sit bottom with one point from their three matches.
