Ferran Torres struck a brace and goals by Ilkay Gundogan, Gabriel Jesus and Rodri helped City record a thumping result against a lacklusture Arsenal side.
Arteta’s side have now lost all three of their Premier League games this season without scoring a goal.

“He cannot use the players that he needs to do [his system]. All the managers need their squads. The depth of their squad.
“All our players except Kevin [de Bruyne] and Phil [Foden] are fit. I can handle that and I can make a better manager of myself.
“Absolutely, I am a big fan of him and I am sure that if they trust him, they are going to do a job.”
