Granit Xhaka is demanding crisis talks with Arsenal ahead of the January market.
The Swiss midfielder, who has been stripped of the Gunners captaincy, said he "can't accept" what has gone on.
Xhaka scored in Switzerland's 6-1 win over Gibraltar on Monday that sent them to the Euro 2020 finals.
He told Swiss broadcaster SRF: "I have a clear idea as to how things should proceed, and Arsenal know this as well.
"Although I still have a contract with them, I will be glad to return to the club - so we can finally sort matters out.
"There will surely be a solution - as I can't accept what has happened with me."
