Mikel Arteta has explained that Alexandre Lacazette is on the bench against Chelsea because he's still feeling a little under the weather after testing positive for COVID-19.
The Frenchman missed the Gunners' clash against Southampton at the weekend, but has made himself available if needed against the Blues.
Speaking to Sky Sports before the game, Arteta said: "Laca is available for a few minutes. He hasn’t done any training, he’s available for 10 minutes. After COVID he’s feeling unwell but wanted to be here for the team."
