The 19-year-old defender missed three months of the season with a broken foot as the Ligue 1 campaign was halted due to the coronavirus pandemic.
There have been no matches in France since the start of March, but Saint-Etienne will meet Paris Saint-Germain in the French Cup final on July 24.
Saliba’s initial loan agreement runs only until June 30, but he could not play for Arsenal if he returned to the Emirates Stadium.
Arteta therefore wants Saliba, who cost Arsenal £ 27 million last July, to stay put and take its place in the flagship event.
“I think he should stay there,” he said when asked about the immediate future of Saliba.
“We have an agreement with Saint-Etienne, he is there all year. He won the right to play in this final if the manager (Claude Puel) wants to do it.
“I think we have to give him the opportunity to do it, to take advantage of it and we can have it after that.”
Although he has remained in France since signing for Arsenal under former head coach Unai Emery, Arteta revealed that he has met Saliba on several occasions and admits that he knows there will be pressure on the French to hit the ground next year.
“I have spoken to her several times,” added Arteta.
“He has also been here a few times. We follow his season. As a young player, he had a difficult season with injuries he suffered, but that is part of his process.
“I know how high his expectations are for him next year, but we have to keep in mind his age and what he has done in the past, and make sure we create the right environment for him so that he can continue as a player. ”
Arsenal will face Norwich, the Premier League cross-country team, on Wednesday night in their first home game since the start of the season.
They will give fitness tests to David Luiz, Mesut Ozil and Lucas Torreira before the Canaries clash, with Cedric Soares also hoping to have recovered from a facial injury to be in the running to make his debut.
