Arsène Wenger has made two changes to his side for Sunday's Premier League game against Crystal Palace. 

Lukas Podolski replaces Serge Gnabry and Alex Oxlade-Chamberlain came in for the suspended Mathieu Flamini.

Nacho Monreal keeps his place ahead of Kieran Gibbs at left-back while 17-year-old Gedion Zelalem was named among the substitutes.
