Xhaka remains upset at being stripped of the captaincy for swearing at Gunners fans four weeks ago.
The midfielder, 27, has not been included in their squad for the four games since his Emirates meltdown during the 2-2 with Crystal Palace.
While on international duty this week, Xhaka rapped: “I have a clear idea how things should proceed as I can't accept what has happened."
Emery admits the player first needs to make his peace with supporters.
The manager said, “He is a good guy and good player. He loves and respects Arsenal and knows that in one game he made a mistake.
“First of all, we do not forget his mistake. That is why I took the captaincy off him as it is better he does not have that responsibility.
“But he has told me he is very convinced to help the team and the objective I am working for is for Granit to have a long future with us."
