Thomas Partey was back in the team, starting alongside Declan Rice and Martin Odegaard.
On the trio, Arteta stated: Yes we have the squad available apart from Jurrien, who is hopefully going to be very soon back with all of us and we have to utilise the players and the quality that we have. We thought it was a really good game for Thomas to come back. He looks like he's in rhythm, he trained really well in the past few days. With the players they have we thought it was the right call to make. He stepped up. He had a great performance. He was really important for the team."
He then added: Everything. Also when you play Declan, Kai and Martin and when you play Emile (Smith Rowe) in there and when you play Jorgi as well for sure because we've won some big games with him in there.
Depends on the game, on the state, on the opponent as well. It's great because everyone feels really important as well. I think that's something really important there.
On the boost of a big 5-0 win, he finished: Great for us obviously and for the confidence and the belief that we can do it as well. That we can come to these stages against big teams and perform and win games the way we've done it tonight. Enjoy it and then it's back to work tomorrow because we have a big one on Sunday and we're going to have to prepare really well to beat them."
