The midfielder has not featured since clashing with supporters after being substituted against Crystal Palace last month.
"They are angry and disappointed, as well we are. We have a very good opportunity to [correct] do that," he told reporters.
"Each match here at the Emirates is very important for that... The players need to feel [fans] backing them.
"Xhaka is in the group and he has the possibility to play. I hope every supporter supports him. Xhaka's comeback is going to be important for us."
