Arsenal boss Mikel Arteta says Gabriel Jesus and Martin Odegaard will make their clash with Brentford.
Odegaard has recovered from a training ground concussion, while Gabriel Jesus is now fully fit after missing for almost a month.
Arteta, on captain Odegaard, said: "Hopefully yes. We have another training session today. But he's been progressing well and hopefully he'll be available.
"Yes (he had concussion) because we didn't know how many days. It depends on certain things. At the end we got more delayed than we wanted but we had to protect the player."
On Gabriel Jesus, he also said: "He is available. He played 96 mins in a really competitive match. We have another session. They had a long flight. I have to see the condition of every single player to make the final call on the line up."
And on Ben White, the manager added: "Hopefully if he's able to train today he'll eligible to play. It's a question mark to find in the next few hours."
