The Gunners were downed 1-0 courtesy of a first-half strike from Lys Mousset.
Speaking after the game, Xhaka said: "They have one chance, they score. We have maybe two or three chances and if we score first maybe the game change.
"It was a great chance for our side. I would say if he scored that maybe the game changes.
"I don't know. We speak always, each training, each away game, each home game. We don't look at the table. It is so, so, so early to look at the table.
"We have to work to improve the things we didn't wrong. I thought we did a lot of things right."
