Arteta told ESPN: "Excitement, goosebumps, wanting the day to arrive, [the feeling] of being very prepared, very convinced and knowing that the opportunity is to play in a Champions [League] final. And when you get to that point, you have to give your life for it."
Speaking about the first leg, he added: "Look, when I was going through the tunnel, I see [Takehiro] Tomiyasu out, [Riccardo] Calafiori out, Gabriel Magalhaes out, Kai Havertz out, Gabriel Jesus out, Thomas Partey out, Jorginho out. Starters!
"And I see the team compete and I get goosebumps. Because we have a lot of merit and yet the game was by very, very, very small margins that weren't on our side that day. That's why I'm very optimistic."
