Arsenal boss Mikel Arteta is not optimistic about Thomas Partey's injury.

The Ghana midfielder limped off in the first half of Sunday's 2-1 friendly loss to Chelsea

Partey appeared to suffer an ankle injury following a tackle by Chelsea forward Hakim Ziyech.

Asked about the former Atletico Madrid man, Arteta said: "At the moment, it's not looking good because he was in pain and he could not continue.

"He'll have a scan tomorrow. At the moment it's not looking good."
