The Gunners swept Inter away 3-1 at San Siro stadium.
Inter goalscorer Petar Sucic said afterwards: "They are a good side and play good football, but we had a good game. We had chances - especially in the first half - but were unable to take them. We should have been more clinical.
"Arsenal have one of the best defences in the world, but we created chances. In football, you have to score. I scored a good goal, but it doesn't matter now."
Piotr Zielinski stated: "We played well overall, but we should have been more focused. We conceded three goals and should have scored more."
Winger Luis Henrique said: "I believe we played great. Arsenal are a strong side and they did better in front of goal. The details made a difference. We needed to be more clinical."
