With Manchester City dominating the summer's transfer headlines with reports of huge fees and wages being offered for top stars, Gazidis has called for a greater responsibility from top-flight clubs.

"I think it is worth our while to investigate whether there are elements of the salary cap system, which they have in US NFL and baseball, which would benefit football," Gazidis told The Guardian.

"Clubs have a duty to provide more stability in our business models and some form of wage restraint is one element worth looking at.

"There are many ways in which it could work."

Gazidis joined Arsenal last year after working as the deputy commissioner of Major League Soccer, which employs a salary cap.
