New Arsenal chief Ivan Gazidis says talk of a salary or scrapping relegation is unrealistic for the Premier League.
"I don't think it would work for a range of different reasons, some of them logistical.
"How do you get your arms around a worldwide market to impose a salary cap, for example? But there are cultural issues also.
"Abandoning promotion and relegation may be a sounder business model, but culturally that is not acceptable."
