The 26-year-old’s match-winning display in les Bleus’ opening World Cup 2014 qualifier against Finland at the Helsinki Olympic Stadium was blighted by a late muscular concern, just weeks after returning for almost a year out.
Diaby has been plagued by injury since fracturing his ankle against Sunderland in 2006 - but Wenger has moved quickly to allay fears of another spell on the sidelines.
"[The injury] doesn't seem serious to me at all. He has a small chance of playing on Saturday," he told TFI.
France boss Didier Deschamps confirmed the setback earlier in the week, telling Eurosport: "Diaby took a bad shot and he has muscular discomfort. He is not free in his movements."
The marauding midfielder has been a stand-out performer for Arsenal in their strong start to the new Premier League season - as the Gunners have notached a win and two draws without conceding a goal in their opening three games.
