Speaking to BBC Match of the Day after the game, Arteta said, "I'm really happy with the performance against a Newcastle team who are really really good. The boys were really good, really aggressive and we deserved to win the game. They [Newcastle] have a lot of resources to create issues but we continued in the same way, we maintained our rhythm and it was a joy to watch the team play.
"We are really happy, we have to continue to do the things that we are doing well. There are still things that we can do better and we are bringing big players back from injury so that is a big boost. Against Porto, we were ourselves with the ball but not without the ball. It was a big lesson and you learn a lot from those moments."
