Arsenal are a better side with Olivier Giroud in it, according to Jermaine Jenas.
The France striker has struggled for game time this season following an extended summer break after his Euro 2016 campaign, and then because of a toe injury.
And despite Arsenal enjoying a string of eight wins in a row and currently sitting joint-top of the Premier League table, Jenas believes that Wenger's side would benefit from having Giroud in it.
"I still think they're better with Giroud in the team," the former Tottenham midfielder told BBC Five Live. "Only because he allows Sanchez, Iwobi, Walcott, Ozil - the three behind him - to play a lot better with him as a focal point."
Jenas is also convinced that Arsenal have the strength in depth to mount a genuine title challenge this season, having previously been limited with their selections.
He added: "Every season there is a worry, 'what if Coquelin gets injured?' or 'what if Giroud gets injured?
"Last week they completely changed their centre-midfield, they went from Xhaka to Elneny - Cazorla played there the week before. Coquelin came in [too]. They've got the ability to do that now.
