Arteta's Arsenal ready to debut Merino

Arteta explains, "We are working to keep him from bothering everyone - the physiotherapists, the doctors, all of them."

"He is ready and he really wants to (play). I think we are comfortable to start exposing him to contact now, and he has looked very good in training."

Arteta then spoke about what Merino can contribute to the team.

"First of all, he has an absolutely incredible football brain.

"He is so intelligent, the way he makes decisions, the way he uses surfaces, and it is very rare to see that."
