For all the turmoil and talk of debt, Manchester United is still the most valuable franchise in all of sports.

Forbes released its list of the world's most valuable teams, with the English Premier League club leading the way at USD1.84b.

The top American franchise, the Dallas Cowboys, was second at USD1.65b. The New York Yankees, Washington Redskins, New England Patriots, Real Madrid, New York Giants, Arsenal, New York Jets and Houston Texans round out the top 10.

Amid protests from fans, Manchester United's owning Glazer family has insisted it will not entertain offers for the club, which has around USD1b of debt.
