Manchester United majority owners the Glazers have been slammed by their Tampa Bay Buccaneers players in a new report.
The NFL Players Association (NFLPA) published annual report cards from the 32 teams in the league.
A total of 1,695 players completed anonymous surveys based on their experiences at their clubs.
The report cards ranked teams based on 11 different categories ranging from ownership and head coaches through to training and weight rooms, food and the treatment of families.
The Glazers were given a D+ ranking after their survey results were collected, with only five other owners receiving a worse score.
