After victory over Olympiakos, Wenger explained: "Eduardo is a quality player. He was not fit enough to start the game today because he had a little muscle problem but we still put him on the bench even though we were scared that he could get injured. But we had no other resources than to bring him on and again he made the difference."
On Theo Walcott, Wenger also revealed: "We played against Olympiacos Under-20s and he played for 60 minutes and came through well. He will be available for England selection and for us on Sunday."
