Arsene Wenger brings Alexis Sanchez back to face Bayern Munich
Sanchez was dropped for the 3-1 defeat to Liverpool on Saturday but returns in place of Olivier Giroud as Arsenal look to overturn a 5-1 deficit in their Champions League second leg tie.
Mesut Ozil, who has missed the last two games with a virsus, has also returned to the matchday squad after Alex Iwobi was forced to pull out through illness.
Goalkeeper David Ospina returns between the sticks as Petr Cech drops to the bench, while Theo Walcott and Aaron Ramsey also come in.
