Arsenal boss Mikel Arteta: "I'm really pleased. It's never easy to come here and win but we dominated the game.
"I said before the game that the game we had here last season was a bad day. it was a building character day. A team has to evolve and take the lesson and move forward.
"In different moments we always stick together. We had 12 first team players in training yesterday but I don't want to use excuses. But you saw today we had some kids."
On Granit Xhaka: "He has got this character and respect and admiration. He has had some difficult days which make him a better person and a better player."
On 15-year-old Ethan Nwaneri making history: "It's great. He deserves it. He has been doing great. He is such a big talent we want to keep with us."
