Jul.17 (GMM) Ferrari has only just scraped into the top-15 in a list of the world's most valuable sports teams.
Forbes magazine said English football club Manchester United tops the list with an estimated worth of $2.23 billion, ahead of Real Madrid and then a roll-call of American football teams.
The Dallas Cowboys is worth $1.85 billion, tied for third with the New York Yankees baseball team.
F1 has only two teams in the top-50, the fabled Italian squad Ferrari ranked fifteenth with an estimated value just over $1 billion.
That is 3 per cent higher than last year, while McLaren's estimated value dropped 2 per cent to $800 million, with Forbes saying main backer Vodafone is reviewing the sponsorship deal.
"McLaren would be hard pressed to replace Vodafone at comparable levels," said Forbes.
"McLaren also faces the free agency of Lewis Hamilton, who is one of the most marketable drivers in the sport," the report added.
