Garde, who played for the Gunners from 1996-99, supported Wenger but believes the club needs more old heads on the pitch.
He told L'Equipe magazine: "Nowadays, Wenger is missing experienced players capable to undergo pressure. He has no more players who can take over on the pitch.
"There were some during my time. If Anelka and Vieira could be so outstanding it was because the pressure was on Adams, Keown, Bergkamp or Wright. Nowadays there is not such a balance anymore."
