Former Arsenal skipper Tony Adams believes that Jack Wilshere should have been insulted by Arsene Wenger's signing of Mesut Ozil last year.
The Gunners broke their transfer record to land the Germany international from Real Madrid for around £42.5m, and the ex-Arsenal captain said that the deal should have acted as a catalyst for Wilshere to show "more fire in his belly".
Adams told The Sun: "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. 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.
"If push came to shove, for a cup final or big match, Arsene would pick Ozil ahead of Jack."
