'It was good to see the impact of the substitutes'
Arsenal boss Mikel Arteta, speaking to BBC Match of the Day: "I think we started really well. The sense I was getting in the last 48 hours after the international break, the boys coming together and were all at it.
"It was good to see the impact of the substitutes [Thomas Partey - goal; Ethan Nwaneri - goal; Raheem Sterling - assist]. Everyone has to feel important. It was a good afternoon."
On Martin Odegaard: "It's not a coincidence. The team flows in a different way when he is playing."
On Ethan Nwaneri: "He is the second youngest [Premier League goalscorer] in our history. That's a story in itself. He's brave. You see the reaction of fans and they were singing 'he's one of our own'. I think we have to put brick by brick and make sure the cement doesn't get dry. Hopefully we can build a beautiful thing with him."
