The Poland international is not happy with the amount of playing time he has earned.
While he could stay and fight for his place, Kiwior thinks it might be time to call it quits.
According to Il Mattino, he is ready to move back to Italy, with the likes of Juventus and Napoli interested.
The two clubs would like to sign him for a reasonable fee, but they may have to pay up to meet Arsenal's demands.
A loan does not seem likely as Arsenal want a sale to fund a replacement vocal.
