Arsenal manager Unai Emery says Granit Xhaka could return against Eintracht Frankfurt on Thursday.
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."
