Former midfielder Emmanuel Petit has claimed that some of Arsenal's first-team squad do not "give 100%" in every match.
On Sunday afternoon, Arsenal suffered their fourth Premier League defeat of the season as the North London outfit lost 3-1 at Manchester City, a result which leaves the club in sixth place in the table.
Petit - who made 116 appearances for the Gunners between 1997 and 2000 - has suggested that motivation has become a problem at the Emirates Stadium, as well as saying that the squad is lacking "spirit".
The 47-year-old told Paddy Power News: "Motivation is a major problem for several of Arsenal's players – it's clear that they aren't always giving 100% out there.
"When the chips are down, several of them keep going missing. Sometimes talent wins you games, but sometimes spirit is also vital."
Arsenal are next in action when they host fierce rivals Tottenham Hotspur on Saturday, November 18.
