Arsenal could rest forward Alexis Sanchez for their final Champions League Group A game at Basel.
The Gunners have qualified for the last 16 and will finish second in the group regardless of their result if Paris St-Germain beat Ludogorets Razgrad.
If Chile international Sanchez is left out, it could provide an opportunity for Spanish striker Lucas Perez.
Midfielder Granit Xhaka returns to his former club Basel, who are vying with Ludogorets for a Europa League place.
The Swiss side must hope Ludogorets of Bulgaria are beaten by French champions PSG and then pick up at least a point.
