The people who run Manchester United work towards the goals they're incentivized to achieve which are determined by the owners and what their priorities are. There isn't a single justifiable reason to keep anyone who works at Utd at executive level if sporting success was important to the Glazers. They see their players as assets, how long they stay is determined by their commercial value, their market value and how much their replacement costs, what happened today and on Sunday would cost most people their jobs and players their careers at clubs who prioritized sporting success as it would be such an obvious failure. It's allowed to persist at Utd because first principles at the club is commercial success and everything is derivative of that. You can't blame Richard Arnold for doing the job he's told to do. The Glazers wanted to put Utd into a league with no relegation and guaranteed revenue, if Utd finished bottom of that league every year, the Glazers wouldn't lose a wink of sleep, they have never felt a duty of care to Utd with regards to what happens on the pitch. Utd are a business with a company football team in a league playing against teams who pour hundreds of millions into winning football games.
