Dani Ceballos will miss Arsenal's Premier League clash against Leicester City at the King Power Stadium on Saturday because of a hamstring injury suffered in Wednesday's UEFA Europa League draw with Vitoria.
The midfielder was substituted in the 54th minute. Shkodran Mustafi opened the scoring in Portugal with 10 minutes to spare, but a goal from Bruno Duarte in the first minute of injury time robbed Arsenal of the full three points:
On Friday, Arsenal confirmed in a club statement that Ceballos will not be available for the visit to Leicester: "Left hamstring. Sustained during the Vitoria match on November 6. Currently being assessed, but will miss Saturday’s match at Leicester City."
Arsenal are enduring a poor spell of form at the moment and are winless in four in all competitions.

He has remained a key player in Unai Emery's side, playing a part in all 11 of Arsenal's Premier League games this term, but he has failed to make good on his early promise.
The Spaniard will be missed against Leicester, though, as he boasts the ability to unlock defences with a single pass, a skill which is lacking elsewhere in the Gunners squad.
