'It's a massive step'
Arsenal manager Mikel Arteta, speaking to TNT Sports: "I'm very happy to win again at home and get a clean sheet, four in a row in the competition. It's a massive step.
"We're very close to achieving the goal we had before the group stage started."
On the collective ambition for goals: "Yes, I'm happy. We generated quite a lot [of chances]. Declan [Rice] especially, but he missed a few big chances, and really good from Martin [Odegaard]. His first goal [and] he really needed that.
"You could tell by the way he celebrated that he had an anger and a desire to do it, so overall a really positive night."
On Declan Rice's goal-scoring potential: "The last few games, he had some big chances. The more consistent he is in those positions, with the quality he has, he will score goals."
