The Gunners icon lead his side to a League and Cup double in 1998 and believes his old side wouldn't have had to sign the German if the England midfielder was pulling his weight
Former Arsenal captain Tony Adams believes Mesut Ozil wouldn't be at the Emirates - if Jack Wilshere was fulfilling his potential.
Adams has accused the England international of letting his talent go to waste, insisting that Arsene Wenger wouldn't have had to bring in the World Cup winner for a club record fee was more focused on and off the field.
The 22-year-old has struggled with injuries and has had his judgement called into question this summer when he was pictured smoling on holiday, and Adams has warned the Wilshere that he risks letting his career go to waste.
"He must show more hunger and professionalism. He's in danger of not fulfilling his potential and his career could be over in the blink of an eye," said Adams in an interview with The Sun
"If push came to shove, for a cup final or big match, Arsene would pick Ozil ahead of Jack.
"He should have taken it as a personal insult that Arsenal went out and signed Ozil when they already had the same talent at their disposal in him.
"He has to be more verbal, shake things up and show more fire in his belly."
Jack Wilshere has made just two appearances for Arsenal in pre-season, following his return from England's World Cup campaign, but could be in line to start in the Community Shield against Manchester City on Sunday.
