The NFL's Dallas Cowboys have been named the world's most valuable sports team after Forbes Business magazine's annual survey.
The new valuation places the Cowboys at the top of the list with a value of £2.6 billion with the NFL side jumping above La Liga giants Real Madrid.
Real Madrid's value now falls £500 million lower than at £2.1 billion with the top five teams including the New England Patriots and the New York Yankees in third and fourth with values of £2.07 billion.

The top five is rounded up with the other Spanish giants Barcelona with a £2 billion value.
Even though the Cowboys have not reached the Super Bowl for 19 years, the team's rise up the rankings has been, as Forbes put it, down to the shrewd business and marketing of the Cowboys owner Jerry Jones.
The highly impressive AT&T Stadium, which records the highest average attendance in the league with 90,000 every home game, helps greatly with the financial strength of Jerry Jones' organisation.
The average value for NFL teams has risen by 38% over the past year with the average sitting at £1.3 billion.
The significant increase comes from the new TV rights that the NFL have agreed, similar to that of the new Premier League TV rights bringing in large amounts of new television money to the teams.
The biggest single year increase in franchise value was the San Francisco 49ers with a 69% increase, this was higher than others due to the teams move to the new Levi's Stadium.
These increases do pose the question as to whether the national football league can keep on increasing its revenues, as the game is faced with increasing commercial breaks within the three hour playing schedules and whether fans will become increasingly disgruntled.
