Aaron Ramsdale, the £30m summer signing from Sheffield United, replaced Leno in the starting line-up on Saturday as the Gunners claimed a 1-0 win over Norwich at the Emirates.
Although Reports in Germany claim Leno has been promised a return to the side for the north London derby against Tottenham on September 26, live on Sky Sports.
However, Arteta insists he hasn’t made any promises to the German goalkeeper about the upcoming derby, or Saturday’s trip to Burnley.
Responding to the reports, Arteta said: “I don’t know where they are coming from but they are ahead of me! “I am the one that picks the team at the weekend and sometimes I read things that I haven’t decided yet. They give me ideas, at most, but I haven’t made a decision for Saturday or the north London derby.”
When asked if he had given Leno any other guarantees about his playing time, Arteta added: “No. That’s what I said to them and I said to the goalkeepers in the last two or three years – that we don’t want to do that.
“What we want to do is empower performance and ask them to train behave and play the best possible way. How can I guarantee somebody something?
“It wouldn’t make sense with what we are demanding them to do. So it is on a daily basis, what you did three months ago in football, it doesn’t count. “So is what you’re going to do today and tomorrow, and that’s it.”
Meanwhile, Arteta has hit back at suggestions Leno reacted badly to being dropped against Norwich and insists the German has acted professionally since the match.
“Obviously for Bernd it wasn’t a pleasing communication when I told him he wasn’t playing but he is a top professional and a top person,” Arteta added.
“He should be disappointed and he should support his team-mates like they’ve done every time he’s played, which is exactly what he’s done.”
