The German playmaker is widely regarded as one of the most technically gifted midfielders in world football but he has often been criticised for failing to produce consistent displays for the north London side.
Ozil is now settling into life under new manager Unai Emery at The Emirates after the Spaniard was brought in as the club’s new manager back in May.
The 29-year-old will be hoping to play an important role for the Gunners as he bids to try and help them break back into the top four this season.
The midfielder has scored two goals in all competitions for the north London side so far this season.
However, former Chelsea FC star Cundy feels that Ozil has never demonstrated the heart and attitude needed to succeed at the very top level.
Speaking in an interview with talkSPORT, Cundy said: “I’ve never said at any point that Ozil is a bad player; we know he’s a good player.
“Technically he’s very gifted; he can (when given time and space) hurt you. The problem I have is his lack of desire and his lack of heart.
“And those two things, I don’t care how much talent you’ve got, unless you have both of those you’re never going to get to the very top.
“People tell me he’s won the World Cup, that he’s the German Player of the Year three, four or five times.
“But I tell you for nothing; one of the reasons Arsenal have done nothing since he’s been there is because of him.”
Meanwhile, Ozil started for the Gunners when they hosed Everton in the Premier League at The Emirates on Sunday afternoon.
They will return to League Cup action on Wednesday night when they host Brentford in the third round this week.
