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.
