Saliba signed for the Gunners last summer before being loaned back for this campaign. The young centre-half has now confirmed he expects to move to London this summer.
"For the moment, I am 300% in Saint-Etienne, I have not put my mind elsewhere. Next season I will be at Arsenal," said Saliba.
"But I'm still following their results."
Saliba and ASSE meet Epinal tonight in the quarterfinals of the Coupe de France.
