Arteta gave updates on a number of players including Martin Odegaard (knee), Declan Rice (thigh), Raya (other) who will all be monitored ahead of the game as they return to the side.
"Martin (Odegaard) is the other one. We will see. We have to wait and see how comfortable he is to do certain actions.
On Declan Rice's availability: "I hope so. He was much better today. We haven't really trained because we only have two days to prepare for the game, so hopefully he is going to be better tomorrow."
On goalkeeper David Raya: "David is good, good to go."
Adam Webster and Stefanos Tzimas are the two long-term casualties for Brighton, with both having undergone knee operations in recent weeks in what will be a veru tough test for manager Fabian Hurzeler.
