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, who 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.
He told TFI "[The injury] doesn't seem serious to me at all. He has a small chance of playing on Saturday."
France boss Dider 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."
Diaby has been a stand-out performer for Arsenal in their strong start to the new Premier League season - notching one win and two draws without conceding a goal in their opening three games.
