It has been talked about so much that fans have been taken aback that he does not yet play for the club.
ESPN have revealed he should be on loan again this season as Arteta believes he needs to learn how to defend set pieces better and also know when to make a tackle instead of just diving into one.
He was supposed to return to Saint-Etienne on loan before the transfer window closed, but that deal was not made on time and he will now have to join an England side.
The report claims both Brentford and Watford are interested in signing him.
Saliba has been seen as the longtime partner of Gabriel Magalhaes who also joined Arsenal this summer and he hopes to make a fairly good impression on Arteta when he leaves on loan.
