Regarding Merino's injury, Arteta said: "Tomorrow is too soon. Next week we’ll see. He had partial training today. It’s about the healing of the bone and seeing when he’s ready for contact."
On Raya, Arteta added: "We have to wait another 24 hours. We have to wait 24 hours to see if it’s looking good or not that good. It’s about a player being fit and available or not. When we have that clarity for Leicester we will make that decision tomorrow.
"Jurrien was able to take part in training today so he’ll be available in the squad. Hopefully Ben too."
