Wenger’s future is uncertain with his contract up in the summer and fan fury boiling over.
Protests have taken place before their last three games starting with the Bayern Munich second leg – which they went on to lose 5-1.
Banners have been displayed, planes have been flown, and Wenger now says he knows what he will do.
Express Sport revealed on Sunday that he will sign a one-year deal and further reports came out last night suggesting he is set to stay.
And Giroud says the squad still has his back.
“We want to see Arsene Wenger sign an extension,” Giroud told French TV channel Canal+.
“To continue the adventure, because we support him.
“We hope to win the Cup and qualify Arsenal for the Champions League.”
Arsenal have dropped to sixth in the league after a horrendous run which has seen them lose six of their last nine games in all competitions.
That runs includes two wins over fifth tier oppositions – Sutton and Lincoln – and two 5-1 defeats to Bayern Munich.
Last night it was reported in Germany that Arsenal had approached Borussia Dortmund boss Thomas Tuchel to take over in the summer, but a club spokesman has denied that story.
And West Brom boss Tony Pulis says Wenger has told him he’s going to stay.
“I’ll be surprised if he goes,” Pulis said after West Brom beat Arsenal on Saturday.
Asked why he thought that, the Baggies boss added: “Because he told me.”
