Arsenal boss Arsene Wenger explained benching Alexandre Lacazette for victory over Everton.
The Gunners thrashed Everton 5-1, with Aaron Ramsey hitting a hat-trick.
On benching Lacazette, Wenger said: "I am very happy with him. We could not afford to let Giroud, Walcott and Sanchez go and bring no one in.
"That is impossible. In the Europa League Aubameyang can not play, there are all kinds of possibilities to give everyone games."
