Arsenal boss Mikel Arteta hailed matchwinner Bukayo Saka after their Europa League victory at Bodo/Glimt.
Saka combined with impressive midfielder Albert Sambi Lokonga and his toe-poked effort hit a defender before ricocheting back off his chin and past the helpless goalkeeper.
Asked about Saka's progress, Arteta declared: “Yes, but again he can become much better. He had moments in the game where he was really good and then moments he can improve and demand more of himself, especially defensively.
"There were moments where we allowed their left full-back to progress the play and break our press too easily. There a lot of things to improve."
On the Europa League helping with Premier League form, he added: "It is two different competitions and approaches. You can see the control, demands and amount of shots that teams produce in the Europe, it is very different but we are adapting to that and I'm happy overall with the way we're performing."
